My daughter needs to Find 4 2/4 - 7/8

3.625

Step-by-step explanation:

Conversion a mixed number 4 2/4

to a improper fraction: 4 2/4 = 4 2/4

= 4 · 4 + 2/4

= 16 + 2/4

= 18/4

To find a new numerator:

a) Multiply the whole number 4 by the denominator 4. Whole number 4 equally 4 * 4/4

= 16/4

b) Add the answer from previous step 16 to the numerator 2. New numerator is 16 + 2 = 18

c) Write a previous answer (new numerator 18) over the denominator 4.

Four and two quarters is eighteen quarters

Subtract: 18/4- 7/8

= 18 · 2/4 · 2- 7/8 = 36/8- 7/8= 36 - 7/8

= 29/8

For adding, subtracting, and comparing fractions, it is suitable to adjust both fractions to a common (equal, identical) denominator. The common denominator you can calculate as the least common multiple of both denominators - LCM(4, 8) = 8. In practice, it is enough to find the common denominator (not necessarily the lowest) by multiplying the denominators: 4 × 8 = 32. In the next intermediate step, the fraction result cannot be further simplified by canceling.

In words - eighteen quarters minus seven eighths = twenty-nine eighths.
