Solve the Division Problem: 72 ÷ 18

We will use the distributive property of division and split the number 72 into a sum of 36 and 36, which makes the division operation easier and allows us to solve the exercise without a calculator.

Note - it's advisable to split the number according to multiples of the divisor. In this case of the number 18 because we need to divide by 18.

Reminder - The distributive property of division actually allows us to split the larger term in the division problem into a sum or difference of smaller numbers, which makes the division operation easier and allows us to solve the exercise without a calculator

We will use the formula of the distributive property

 (a+b):c=a:c+b:c 

$72:18=(36+36):18$

$(36+36):18=36:18+36:18$

$36:18+36:18=2+2$

$2+2=4$

Therefore the answer is option B - 4.
