What is the largest multiple of 9 which is smaller than -70?

The number is -72

Step-by-step explanation:

We want the largest multiple of 9 (this is a number equal to 9*r, where r is a real number) that is smaller than -70

So we want the first multiple of 9 that is smaller than -70.

We have that 9*8 = 72

so we will also have that 9*-8 = -72

now, -72 is smaller than - 70

-72 is a multiple of 9.

-72 is the first multiple of 9 smaller than -70 (the next is 9¨-9 = -81 ) so we have that -72 is the largest multiple of 9 that is also smaller than -70.
