2 1/16 = d + 5 7/16

d= 3 1/4?

No.

You need to subtract 5 7/16 from both sides of the equation.

Your answer will be a negative number.

no

- 3 1/4?

You're close. I get - 3 6/16 = -3 3/8

To verify if d = 3 1/4 satisfies the equation 2 1/16 = d + 5 7/16, we can substitute the value of d into the equation and check if both sides are equal.

First, let's convert the mixed numbers into improper fractions:
2 1/16 = 33/16
5 7/16 = 87/16

Now we can substitute the value of d = 3 1/4 into the equation:
33/16 = (3 1/4) + (87/16)

To add mixed numbers with fractions, we need to convert the mixed numbers into improper fractions. Therefore, we have:
33/16 = (13/4) + (87/16)

To add fractions with different denominators, we need to find a common denominator. In this case, the common denominator is 16. Therefore, we have:
33/16 = (52/16) + (87/16)

Now, we can add the fractions:
33/16 = 52/16 + 87/16
33/16 = (52 + 87)/16
33/16 = 139/16

As both sides of the equation are equal, we can conclude that d = 3 1/4 (or 13/4) is indeed a valid solution for the equation 2 1/16 = d + 5 7/16.
