Answer 1

7/6*8+11/6*6=(7*6+11*8)/6*6*8= 130/288   =65/144
26/9*5-15/6*5=(26*6-15*9)/6*5*9=21/6*5*9=7/90
13/6*3-5/6*4=(13*4-5*3)/6*4*3=37/72
309/25+382/50=(618+382)/50=1000/50=100/5=20
103/20-47/10=(103-94)/10=9/10
45/2*2+37/2*5=(45*5+37*2)/20=299/20=14 19/20
11/9*7-1/9= (11-7)/9*7=4/63

Answer 3

To solve the given expression, let's break it down step by step:

Addition and Subtraction of Fractions:

We have the following fractions to add and subtract: - 7/48 - 11/36 - 26/45 - 16/30 - 13/18 - 5/24 - 9/25 - 32/50 - 3/20 - 7/10 - 11/63 - 1/9

To add or subtract fractions, we need to find a common denominator. In this case, the least common multiple (LCM) of the denominators will serve as the common denominator.

The LCM of 48, 36, 45, 30, 18, 24, 25, 50, 20, 10, 63, and 9 is 2520.

Now, let's convert each fraction to have a denominator of 2520:

- 7/48 = (7 * 52) / (48 * 52) = 364/1248 - 11/36 = (11 * 70) / (36 * 70) = 770/2520 - 26/45 = (26 * 56) / (45 * 56) = 1456/2520 - 16/30 = (16 * 84) / (30 * 84) = 1344/2520 - 13/18 = (13 * 140) / (18 * 140) = 1820/2520 - 5/24 = (5 * 105) / (24 * 105) = 525/2520 - 9/25 = (9 * 100) / (25 * 100) = 900/2520 - 32/50 = (32 * 50) / (50 * 50) = 1600/2520 - 3/20 = (3 * 126) / (20 * 126) = 378/2520 - 7/10 = (7 * 252) / (10 * 252) = 1764/2520 - 11/63 = (11 * 40) / (63 * 40) = 440/2520 - 1/9 = (1 * 280) / (9 * 280) = 280/2520

Now, we can add and subtract the fractions:

(364/1248) + (770/2520) + (1456/2520) - (1344/2520) + (1820/2520) - (525/2520) + (900/2520) + (1600/2520) + (378/2520) - (1764/2520) + (440/2520) - (280/2520)

Simplifying the Expression:

To simplify the expression, we can combine the numerators and keep the common denominator:

(364 + 770 + 1456 - 1344 + 1820 - 525 + 900 + 1600 + 378 - 1764 + 440 - 280) / 2520

Now, let's perform the calculations:

364 + 770 + 1456 - 1344 + 1820 - 525 + 900 + 1600 + 378 - 1764 + 440 - 280 = 1035

Therefore, the simplified expression is:

1035/2520

Please note that the answer has been simplified as much as possible.
