JANE SCORCES 17 OUT OF 25 IN A MATHS TEST.
WHAY PERCENTAGE DID SHE GET??
ANSWER IS 68%
Test is out of 25. But Percentage means out of 100.
25 x 4 = 100
So... 17 x 4 = 68

WHICH OF THE FOLLOWING HAS THE LARGEST VALUE?
5/7, 71%, 0.69, 2/3, 65%
Well 2/3 is 1/3 doubled... i know this is 0.66666
65% is 0.65
0.69 is 0.69
71% is 0.71
so we've got 0.71 as the max so far
Now... 5/7 looks tricky...
long division.. 0.71+a bit
So... 5/7
Only my attempts and i'm not a tutor just a parent
