Question

3/2 * 6/5 + 5/6 - 3/10 + 42/25

Answer 1

Ответ будет равен:4 целых 1/75

Answer 2

To solve the expression, follow the order of operations (PEMDAS/BODMAS):

1. Perform multiplication and division from left to right.
2. Perform addition and subtraction from left to right.

Let's calculate the expression step-by-step:

Step 1: 3/2 * 6/5 = 18/10 = 9/5

Step 2: 9/5 + 5/6 = (54/30) + (25/30) = 79/30

Step 3: 79/30 - 3/10 = (79/30) - (9/30) = 70/30 = 7/3

Step 4: 7/3 + 42/25

To add fractions with different denominators, we need to find a common denominator. In this case, the common denominator is the least common multiple (LCM) of 3 and 25, which is 75.

Step 5: Convert both fractions to have a denominator of 75:

(7/3) * (25/25) = 175/75

(42/25) * (3/3) = 126/75

Step 6: Add the fractions:

175/75 + 126/75 = 301/75

So, the final result is 301/75.
