Stuck on maths

[daniel]

Hello everyone

I am stuck on some maths questions and appreciate if someone would help me. I am taking the bishop vesey test in October.

Q1. Convert this recipe for pasta from imperial to metric units (to the nearest 5 g). Use the approximation of 102 = 30g

Ingreidient Imperial Metric
Plain flour 5oz ?
Semolinal Flour 12oz ?

Q2. 36 Posts were spaced evenly along a road 1.575 km long. what was the distance in metres between each pair of posts?

Q3. books cost seven pence more than comics. Two books and one comic cost 53 pence. How much for one comic?

Thankyou
Daniel

Hi Daniel

Q.1 The conversion is probably 1oz = 30g not 102 = 30g

Plain flour 5oz = 5 x 30g = 150g

Semolina flour 12oz = 12 x 30g = 360g

Q2
If there are 36 posts then there are 35 spaces.

1.575 divided by 35 = 0.045 km

There are 1000 metres in 1 kilometre, so the posts are 45 metres apart.

Q3
We don´t know the value of the comic, so give it a value of x.

The books are 7p more than the comic, so call this x + 7

Two books = x + 7 + x + 7
One comic = x

Simplify this information to 3x + 14

Giving the equation 3x + 14 = 53

Subtract 14 from both sides, giving

3x = 39

Divide both sides by 3 giving

x = 13

One comic = 13p

Thankyou so much for your help, I was really stuck on these questions and my dad couldnt help me he is not very good at maths.


Thankyou

Hi Mike

Just one other question please, I cant figure this one out. I am really puzzled.

There are twice as many 5p coins as 2p coins and twice as many 2p coins as 1p coins.

This means there are:

---?----5p coins ----?----2p coins ----?---1 pcoins

Thankyou

[Mary B]

This means for every 1p coin, there are two 2p coins and four 5p coins.

Sorry I didnt write the full question in my other message. Please help with the question below.

A cash box contains some coins to the value of £5.25

There are twice as many 5p coins as 2p coins and twice as many 2p coins as 1p coins.

This means there are:

---?----5p coins ----?----2p coins ----?---1 pcoins

Thankyou

Hi Daniel

Check the question again, I think you are trying to make 6.25.

That is 25 x 1p 25p
50 x 2p 100p
100 x 5p 500p

Aplogies, I do not have a pound sign on my keyboard!!

The 1p must be a multiple of 5 ending in 5

so the options can only be 5, 15, 25, 35 etc.

Regards

Mike

Hi Mike

the question is correct, it is taken from the Bond forth maths assesment papers p30.

I cant seem to work this one out, I am worried that a similar question might be in the real test.

Thanks
Daniel

Hallo Daniel
Yes - I have the book here.......it is Paper 11, right?
All I have is my sons answers, and they are
84x5p
42x2p
21x1p
Which is the correct answer, but does not give you a mathematical equation to work on.
Personally I havent a clue, but if no one else has answered today, I will find out how it is done (apart from guessing) and get back to you.
Good luck- some of those questions are tricky arent they?

If you look at Mary B 's reply, if you add up one 1p, two 2p's & 4 5p's the total is 25p. Divide 25p into £5.25 and you get 21 lots of 25p.
So multiply the original 25p pile of coins by 21 and you get 21 1p's, 42 2p's and 84 5p's.
Hope this makes sense!
