write a number model to estimate the answer.
18.7 = 74.8 / 4
19 = 80/4
To estimate the answer to the equation 18.7 = 74.8 / 4, we can use rounding.
First, divide 74.8 by 4:
74.8 / 4 = 18.7
Now, let's round the numbers:
18.7 rounds to 19
So, an estimated number model for the equation 18.7 = 74.8 / 4 would be:
19 = 19
Remember, this is just an estimate obtained by rounding the numbers. The exact answer is 18.7 = 74.8 / 4.
