Question

roshni bought a material length of 3 2/5 and one more piece of length 2 7/10 .how much did she purchased in all ?

Answer 1

The total length of the material purchases = $6 \frac{1}{10}$ units.

Step-by-step explanation:

Given:

Length of material bought first = $3\frac{2}{5}$ units

Length of the second material = $2\frac{7}{10}$ units

To begin, we must first convert mixed fractions to improper fractions.

$3\frac{2}{5} =$ (5*3) + 2 = 17 = $\frac{17}{5}$ units

$2\frac{7}{10} =$ (10*2) + 7 = 27 = $\frac{27}{10}$ units

To find the total length, we add both the lengths

Total length = $\frac{17}{5} + \frac{27}{10}$

Total length = $\frac{(17*2) + 27}{10}$

Total length = $\frac{34 + 27}{10}$

Total length = $\frac{61}{10}$ = $6 \frac{1}{10}$ units
