Answer 2

Answer:

The value of  $\frac{7}{8}$ × $\frac{4}{21}$ =  $\frac{1}{6}$

Step-by-step explanation:

Given numbers are $\frac{7}{8}$ and $\frac{4}{21}$

Required to find the product of the numbers $\frac{7}{8}$ × $\frac{4}{21}$

Recall the concept

The product of a fraction =  $\frac{product \ of\ \ numerators}{product \ of \ denominators }$

Solution

Numerators are  7 and 4

denominators are 8 and 21

∴ $\frac{7}{8}$ × $\frac{4}{21}$ =  $\frac{7X4}{21X8}$

Canceling the common terms 7 and 4 we get

$\frac{7}{8}$ × $\frac{4}{21}$  = $\frac{1}{6}$

∴The product of minus 7 upon 8 and 4 upon 21​ = $\frac{1}{6}$
