Question

Can anyone help my little sister with her math I tried helping her but I couldn’t figure out how to do the math!!

Answer 1

1 3.725 kg of wood

2 10

Explanation:

For question 1 you multiply the total weight by 3/4 to find the weight of the metal, you then subtract this from the total to find the weight of the wood

For question 2 you look at it as a fraction 1/3 kids + 2/3 adults equal 30, since there are twice as many adults. Then you multiply 30 by 1/3 and get 10

Answer 2

1: the wooden part is 3.725 kilograms.

2: 10 Children
