Question

Fill in the blanks to make each of the following a true statement :

$65\times 28=65\times 20+\_\_\_\times 8$

Answer 1

Using the distributive property of multiplication over addition of whole numbers: $\mathrm{a}\times \left(\mathrm{b}+\mathrm{c}\right)=\mathrm{a}\times \mathrm{b}+\mathrm{a}\times \mathrm{c}$,
Hence, we have

$65\times 28=65\times \left(20+8\right)=65\times 20+65\times 8$
