48 feet
Divide 858 by 18 to get 47.6 > simplify > 48 feet
I’m not entirely sure how to answer this without a word problem, but from what I see, all you have to do is multiply the two numbers.
12 x 43= 516
5 x 88 = 440
8x 63= 504
7 x 28= 196
Usually, when you see a number followed by another number in parentheses, like here, that means to multiply.
