Hi

Can someone explain an easy method to do the problem below. DC understands the concept but is taking time to calculate

Q 45 This is part of a conversion table for pounds to kgs and Kgs to pounds. As an example 3 pounds = 1.36 Kg

pounds to kg kg to pounds
1 0.45kg 2.21 lbs
2 0.91kg 4.41 lbs
3 1.36kg ?
4 1.81kg 8.82 lbs

What figure is missing from the table?

It's 1 and 2 added together

Thankyou. It is funny how you sometimes miss something so simple
