Question

17/28+х=-1 1/7+ 2 1/2

Answer 1

17/28 +х=-1/7+1,
17/28+х=6/7,
х=6/7-17/28,
х=1/4

Answer 2

Let's solve the given equations step by step:

1. 17/28 + x = -1

To solve for x, we'll isolate x on one side of the equation.

Subtract 17/28 from both sides:

x = -1 - 17/28

To simplify the right-hand side, we need a common denominator, which is 28 in this case:

x = (-28/28) - (17/28)

x = (-28 - 17) / 28

x = -45/28

So the value of x is -45/28.

2. 1/7 + 2 1/2

To add these two fractions, we need a common denominator. The denominator for 1/7 is 7, and for 2 1/2 (or 5/2) is 2:

1/7 + 5/2

To find a common denominator, multiply the first fraction by 2/2:

(1/7)*(2/2) + 5/2

2/14 + 5/2

Now that we have a common denominator, we can add the fractions:

2/14 + 35/14

Combine the numerators:

(2 + 35) / 14

37/14

So, 1/7 + 2 1/2 = 37/14.

To summarize:

1. x = -45/28
2. 1/7 + 2 1/2 = 37/14
