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:

$\begin{gathered} 2\frac{7}{8}-\frac{15}{16} \\ \\ 1\frac{1}{5}\times2\frac{1}{3} \\ \\ \frac{2\frac{1}{5}}{4} \end{gathered}$

We are asked to evaluate each of them.

Step 1:

we shall convert each fraction into an improper fraction.

$\frac{23}{8}-\frac{15}{16}$$\frac{46-15}{16}=\frac{31}{16}=1\frac{15}{16}$$\begin{gathered} 1\frac{1}{5}\times2\frac{1}{3} \\ \\ \frac{6}{5}\times\frac{7}{3}=\frac{2\times7}{5}=\frac{14}{5}=2\frac{4}{5} \end{gathered}$$\frac{2\frac{1}{5}}{4}=\frac{\frac{11}{5}}{4}=\frac{11}{5}\times\frac{1}{4}=\frac{11}{20}$
