Round down the numbers to the nearest ten and estimate the value of the expression. 2831 1/7 + 3431 5/6 + 6741 + 308 1/5
最佳解答:
2831 1/7 ~ 2830 3431 5/6 ~ 3430 6741 ~6740 308 1/5 ~ 308 Therefore, 2831 1/7 + 3431 5/6 + 6741 + 308 1/5 ~ 2830 + 3430 +6470+3080 =15810
其他解答:
2831 1/7 ~ 2830 3431 5/6 ~ 3430 6741 ~6740 308 1/5 ~ 300 Therefore, 2831 1/7 + 3431 5/6 + 6741 + 308 1/5 ~ 2830 + 3430 +6470+300 =13030
