Question

4 - 1 3/5 + 10 3/4=. 3 3/8+5 7/8-4 1/2 =​

Answer 1

Ответ:

$4-1\frac{3}{5}+10\frac{3}{4} =4-\frac{8}{5} +\frac{43}{4}=\frac{80-32+215}{20} =\frac{263}{20} =13\frac{15}{100} =13\frac{3}{20}$

$3\frac{3}{8}+5\frac{7}{8}-4\frac{1}{2}=\frac{27}{8} +\frac{47}{8}-\frac{9}{2}=\frac{27+47-36}{8} =\frac{38}{8}=4\frac{3}{4}$

Answer 2

Ответ:   4-1.6+10.75=13.15

3 3/8+5 7/8-4 1/2= 8 10/8- 4 1/2= 4 10-4/8= 4 6/8

Answer 3

Let's solve each of these equations step by step:

1. 4 - 1 3/5 + 10 3/4:

   First, subtract 1 3/5 from 4: 4 - 1 3/5 = 4 - (1 + 3/5) = 4 - 8/5 = (20/5) - (8/5) = 12/5

   Now, add 10 3/4 to the result: 12/5 + 10 3/4 = 12/5 + (10 + 3/4) = 12/5 + (40/4 + 3/4) = 12/5 + 43/4

   To add these fractions, we need a common denominator, which is 20: (12/5) + (43/4) = (12/5) + (43/4) * (5/5) = (12/5) + (215/20)

   Now, add the fractions: (12/5) + (215/20) = (48/20) + (215/20) = 263/20

2. 3 3/8 + 5 7/8 - 4 1/2:

   First, add 3 3/8 and 5 7/8: 3 3/8 + 5 7/8 = (3 + 5) + (3/8 + 7/8) = 8 + (10/8) = 8 + 1.25

   Now, subtract 4 1/2 from the result: 8 + 1.25 - 4 1/2 = (8 + 1.25) - (4 + 1/2) = 9.25 - (4 + 1/2)

   To subtract these mixed numbers, we need a common denominator, which is 2: 9.25 - (4 + 1/2) = 9.25 - (8/2 + 1/2) = 9.25 - 9/2

   Now, subtract the fractions: 9.25 - 9/2 = 9.25 - 4.5 = 4.75

So, the solutions are:

1. 4 - 1 3/5 + 10 3/4 = 263/20
2. 3 3/8 + 5 7/8 - 4 1/2 = 4.75
