Rewrite the division as a multiplication.

72/-18=72/18=72*1/4
Type a fraction. is this right

Your symbolism is absolutely not standard.

For instance,

what happened to the negative sign in the denominator?

72/-18=72/18 is just not true.
Secondly,
This is silly. How can 18 be 4?
72/18=72*1/4

What would be wrong with 72* 1/18 ? (assuming the sign was right, which I think it is not)

Surely your text has examples on this.

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.
