Answer 1

А) 2 целых 3/4 + 1 целая 2/3

To add 2 whole numbers with fractions, you first add the whole numbers and then add the fractions separately.

For the whole numbers, 2 + 1 = 3.

For the fractions, 3/4 + 2/3, you need to find a common denominator. The least common multiple of 4 and 3 is 12.

Converting 3/4 to twelfths: Multiply the numerator and denominator by 3, so 3/4 becomes 9/12.

Converting 2/3 to twelfths: Multiply the numerator and denominator by 4, so 2/3 becomes 8/12.

Now you can add the fractions: 9/12 + 8/12 = 17/12.

Therefore, the sum of 2 whole 3/4 and 1 whole 2/3 is 3 17/12.

Б) 8 целых 3/5 + 1 целая 9/10

Again, start by adding the whole numbers: 8 + 1 = 9.

For the fractions, 3/5 + 9/10, you need to find a common denominator. The least common multiple of 5 and 10 is 10.

Converting 3/5 to tenths: Multiply the numerator and denominator by 2, so 3/5 becomes 6/10.

Now you can add the fractions: 6/10 + 9/10 = 15/10.

Since 15/10 can be simplified, divide the numerator and denominator by their greatest common divisor, which is 5. This gives you 3/2.

Therefore, the sum of 8 whole 3/5 and 1 whole 9/10 is 9 3/2.
