What is an estimate for each expression 1/ 8+2/5,13/4-1/10 and 1/12+1/20 I
To estimate the value of each expression, you can round the fractions to the nearest whole number.
1/8 + 2/5:
Rounding 1/8 to the nearest whole number, we get 0. Rounding 2/5 to the nearest whole number, we get 0. Therefore, the estimate for this expression would be 0.
13/4 - 1/10:
Rounding 13/4 to the nearest whole number, we get 3. Rounding 1/10 to the nearest whole number, we get 0. Therefore, the estimate for this expression would be 3.
1/12 + 1/20:
Rounding 1/12 to the nearest whole number, we get 0. Rounding 1/20 to the nearest whole number, we get 0. Therefore, the estimate for this expression would be 0.
So the estimates for each expression are:
1/8 + 2/5 = 0
13/4 - 1/10 = 3
1/12 + 1/20 = 0
