Question

Reduce to lowest terms1. 60 feet in 4 minutes2. 48 books for 16 students3. 56 children from 14 families please explain so a 7th grader can understand

Answer 1

Step-by-step explanation:

1. 60 feet in 4 minutes

This can be evaluated below as

`\begin{gathered} 60feet=4minutes \\ xfeet=1minute \\ cross\text{ multiply, we will have} \\ 4x=60 \\ (4x)/(4)=(60)/(4) \\ x=15 \end{gathered}`

Hence,

The expresison is reduced to

`\begin{gathered} 60feet\text{ }in\text{ }4minutes \\ 15feet\text{ }in\text{ }1minute \end{gathered}`

2. 48 books for 16 students

`\begin{gathered} 48books=16students \\ xbooks=1student \\ cross\text{ multiply, we will have} \\ 16x=48 \\ (16x)/(16)=(48)/(16) \\ x=3 \end{gathered}`

Hence,

The expression is reduced to

`\begin{gathered} 48books\text{ }for\text{ }16students \\ 3books\text{ }for\text{ }1student \end{gathered}`

3. 56 children from 14 families

This can be reduced to

`\begin{gathered} 56children=14families \\ xchildren=1family \\ cross\text{ }multiply,we\text{ will have} \\ 14x=56 \\ (14x)/(14)=(56)/(14) \\ x=4 \end{gathered}`

Hence,

The final answer is

`\begin{gathered} 56children\text{ }from\text{ }14families \\ 4children\text{ }from\text{ }1family \end{gathered}`
