Question

4,86+12,347+5,14
0,25•7,38•40
3 7/8•16
вычислите

Answer 1

▪4,86+12,347+5,14 = 4,86 + 5,14 + 12,347 = 10 + 12,347 = 22,347

▪0,25 × 7,38 × 40 = 0,25 × 40 × 7,38 = 10 × 7,38 = 73,8

▪
$3 frac{7}{8} times 16 = 3 times 16 + frac{7 times 16}{8} = 48 + 7 times 2 = 48 + 14 = 62$
или другой вариант вычисления:
$3 frac{7}{8} times 16 = frac{31 times 16}{8} = 31 times 2 = 62$
