Question

3 3/4-y=1 1/8 решите пж​

Answer 1

У= 3 3/4-1 1/8
У= 3 6/8-1 1/8
У= 2 4/8
У= 2 1/2

Answer 2

To solve the equation, we need to isolate the variable "y". Let's go through the steps:

Given equation: 3 3/4 - y = 1 1/8

Step 1: Convert the mixed numbers to improper fractions: 3 3/4 = (4 * 3 + 3)/4 = 15/4 1 1/8 = (8 * 1 + 1)/8 = 9/8

The equation becomes: 15/4 - y = 9/8

Step 2: Make the denominators the same: Since the denominators are already different, we need to find a common denominator. In this case, the least common multiple (LCM) of 4 and 8 is 8.

Multiply the first fraction by 2/2 (equivalent to 8/8) and the second fraction by 1/2: (15/4) * (2/2) - y = (9/8) * (1/2) 30/8 - y = 9/16

Step 3: Combine like terms: 30/8 - y = 9/16

Step 4: Move the variable term to the other side:

• y = 9/16 - 30/8

Step 5: Simplify and find a common denominator:

• y = (9/16) - (30/8) = (9/16) - (60/16) = -51/16

Step 6: Solve for y: To isolate the variable y, we multiply both sides of the equation by -1 to change the sign: -1 * (-y) = -1 * (-51/16) y = 51/16

Therefore, the solution to the equation is: y = 51/16
