Use the number bonds to help you find the missing numbers in the equations.
The first number bond tells us that nine is equal to five plus four. This means that nine multiplied by four is the same as five plus four multiplied by four. Using the distributive property of multiplication, this is equal to five multiplied by four plus four multiplied by four. The missing number in the first line of our equation is four.
Five multiplied by four is equal to 20, and four multiplied by four is 16. Therefore, the missing number in the second line is 16. Adding 20 and 16 gives us an answer of 36, which is equal to nine multiplied by four. The three missing numbers in the equations are four, 16, and 36.
