4-x I know this because my teacher just went over this problem
There are 4 multiples of 5 between 1-20 5.10.15.20 which are 4/20 aka 1/5 so 1/5 of 200 is 20 times Yaga yeet
To estimate the quotient, we first round off the divisor and the dividend to the nearest tens, hundreds, or thousands and then divide the rounded numbers. In a division sum, when the divisor is made up of 2 digits or more than 2 digits, it helps if we first estimate the quotient and then try to find the actual number.
