Question

А)5+1\4. Б)4+3/7. В)3+3/5. Г)12+15/17

Answer 1

$5+ \frac{1}{4}= \frac{20+1}{4}= \frac{21}{4}=5 \frac{1}{4} = 5,25$
$4+ \frac{3}{7} = \frac{28+3}{7} = \frac{31}{7}= 4 \frac{3}{7}$
$3 +\frac{3}{5} = \frac{15+3}{5}= \frac{18}{5} = 3 \frac{3}{5} =3,6$
$12+ \frac{15}{17} = \frac{204+15}{17} = \frac{219}{17} =12 \frac{15}{17}$

Answer 2

A) 5,25 Б) 4 3/7 В) 3,6 Г) 12 15/17

Answer 3

Let's solve each of the given expressions:

А) 5 + 1/4 To add these fractions, we need to find a common denominator. The common denominator is 4. So, we rewrite 5 as a fraction with a denominator of 4: 5 = 20/4

Now, the expression becomes: 20/4 + 1/4 = (20 + 1) / 4 = 21 / 4

The result is 21/4.

Б) 4 + 3/7 There's no need to find a common denominator here since the denominators are already the same. We can directly add the whole numbers and fractions:

4 + 3/7 = (4 * 7 + 3) / 7 = (28 + 3) / 7 = 31 / 7

The result is 31/7.

В) 3 + 3/5 We need to find a common denominator, which is 5. So, we rewrite 3 as a fraction with a denominator of 5: 3 = 15/5

Now, the expression becomes: 15/5 + 3/5 = (15 + 3) / 5 = 18 / 5

The result is 18/5.

Г) 12 + 15/17 There's no need to find a common denominator here since the denominators are already the same. We can directly add the whole number and the fraction:

12 + 15/17

The result is 12 + 15/17. This expression cannot be simplified further without additional information.

So, the final results are: А) 5 + 1/4 = 21/4 Б) 4 + 3/7 = 31/7 В) 3 + 3/5 = 18/5 Г) 12 + 15/17 = 12 + 15/17
