Question

3 3/4 * 1 1/5 + (2,55 + 2,7) : (0,1 - 1/80)По действиям плииз♥♥

Answer 1

3 3/4 * 11/5 + (2,55+2,7):(0,1-1/80)=
3,75*2,2 + (2,55+2,7)/(0,1- 0,0125)=
2,55+2,7=5,25
0,1-0,01125= 0,08875
5,25/0,08875= 59,15492958
3,75*2,2=8,25
8,25+59,15492958= 67,40492958

Answer 2

Sure, let's solve the expression step by step:

1. Convert the mixed fractions to improper fractions: 3 3/4 = (4 * 3 + 3) / 4 = 15/4 1 1/5 = (5 * 1 + 1) / 5 = 6/5

2. Perform the multiplication and addition first: 3 3/4 * 1 1/5 = (15/4) * (6/5) = 90/20 = 9/2 = 4.5

3. Calculate the values in the parentheses: (2.55 + 2.7) = 5.25

4. Convert the decimals to fractions: 2.55 = 2 55/100 = 2 11/20 2.7 = 2 7/10 = 2 14/20

5. Perform the subtraction: 0.1 - 1/80 = 1/10 - 1/80 = 8/80 - 1/80 = 7/80

6. Convert the result back to a decimal: 7/80 = 7 ÷ 80 = 0.0875

7. Perform the division: (5.25) / (0.1 - 1/80) = 5.25 / 0.0875 = 60

8. Finally, add the results of the previous steps: 4.5 + 60 = 64.5

The final result of the expression is 64.5.
