How to slove these problems2 7/8 - 15/161 1/5 x 2 1/32 1/5 ./. 4

Answer 1

The Solution:

Given the following:

`\begin{gathered} 2(7)/(8)-(15)/(16) \\ \\ 1(1)/(5)*2(1)/(3) \\ \\ (2(1)/(5))/(4) \end{gathered}`

We are asked to evaluate each of them.

Step 1:

we shall convert each fraction into an improper fraction.

`(23)/(8)-(15)/(16)`
`(46-15)/(16)=(31)/(16)=1(15)/(16)`
`\begin{gathered} 1(1)/(5)*2(1)/(3) \\ \\ (6)/(5)*(7)/(3)=(2*7)/(5)=(14)/(5)=2(4)/(5) \end{gathered}`
`(2(1)/(5))/(4)=((11)/(5))/(4)=(11)/(5)*(1)/(4)=(11)/(20)`
