What is 3 fourths plus 2 and one fourth plus 3 fourths plus 9 sixtenths?

Answer 1

3/4 + 2 1/4 + 3/4 + 9/16

~

Begin by making all mixed numbers improper fractions

2 1/4 --> (2*4+1)/4 --> 9/4

3/4 + 9/4 + 3/4 + 9/16

~

Next, make all denominators the same by finding a common denominator (in this case, 16)

3/4 * 4/4 --> 12/16

9/4 * 4/4 --> 36/16

3/4 * 4/4 --> 12/16

12/16 + 36/16 + 12/16 + 9/16

~

Now add all of the numerators

(12+36+12+9)/16

(69)/16

69/16

Either leave the answer as 69/16 or use a calculator to find: 4.3125
