Sarita bought $\dfrac{2}{5}$ meter of ribbon and Lalita $\dfrac{3}{4}$ meter of ribbon. What is the total length of the ribbon they bought?.


Use "/" to separate numerator and denominator.

The correct answer is 23/20

Length of ribbon bought by Sarita = $\dfrac{2}{5}$

Fraction of cake Najma got = $\dfrac{3}{4}$


Total length of ribbon bought by both of them = $\dfrac{2}{5}$ + $\dfrac{3}{4}$

= $\dfrac{(2 \times 4) + (3 \times 5)}{20}$
= $\dfrac{8 + 15}{20}$ = = $\dfrac{23}{20}$


∴ Total length of the ribbon bought by both Sarita and Lalita is $\dfrac{23}{20}$ meter
