To rewrite the division as a multiplication, you can use the reciprocal (also called the multiplicative inverse) of the divisor. In this case, the division is 72/-18.
To find the reciprocal of -18, you need to find the number that, when multiplied by -18, equals 1. The reciprocal of a number 'a' is represented as 1/a. So, the reciprocal of -18 is -1/18.
Now, you can rewrite the division as a multiplication by multiplying the dividend (72) by the reciprocal (-1/18):
72/-18 = 72 * (-1/18)
This gives you the answer of -4 when you simplify the multiplication.
Therefore, the correct way to rewrite the division 72/-18 as a multiplication is 72 * (-1/18) = -4.
As for typing a fraction, you can simply type the numerator followed by a forward slash (/) and the denominator. For example, to represent the fraction one-fourth, you can type 1/4.
