Question

4 2/7: 3 3/4= Решение

Answer 1

30\7:15\4 = 30\7 * 4\15 = 2\7* 4\1 = 8\7= 1 1\7

Answer 2

4 2/7 + 3 3/4

First, convert the mixed numbers to improper fractions: 4 2/7 = (4*7 + 2)/7 = 30/7 3 3/4 = (3*4 + 3)/4 = 15/4

Now, add the fractions: 30/7 + 15/4

To add these fractions, we need to find a common denominator. The least common multiple of 7 and 4 is 28.

So, we rewrite the fractions with the common denominator: 30/7 * 4/4 = 120/28 15/4 * 7/7 = 105/28

Now, add the fractions: 120/28 + 105/28 = 225/28

Finally, convert the improper fraction back to a mixed number: 225 ÷ 28 = 8 with a remainder of 13 So, 225/28 = 8 13/28

Therefore, 4 2/7 + 3 3/4 = 8 13/28 or 8 1/28.
