What number should be added to 7/12 to get 4/15?​

Mathematics

DENIUS [597]3 years ago
6 0

Answer:

Step-by-step explanation:

Let the number = x.

We are trying to find out what number (x) we would need to add to 7/12 to get 4/15

\frac{7}{12}  + x = \frac{4}{15}

Subtract 7/12 from both sides.

x = \frac{4}{15}  - \frac{7}{12}

We need to make the denominators of the fractions the same.

\frac{4}{15}  = \frac{16}{60}

\frac{7}{12}  = \frac{35}{60}

So,

x = \frac{16}{60}  - \frac{35}{60}  = -  \frac{19}{60}

9 1/2 yards x 19 1/4 yards
saul85 [17]

Answer:

(9 1/2) * (19 1/4) = 1463/8 = 182 7/8

Step-by-step explanation:

Conversion a mixed number 9 1/2

to a improper fraction: 9 1/2 = 9 1/2

= 9 · 2 + 1/2

= 18 + 1/2

= 19/2

To find a new numerator:

a) Multiply the whole number 9 by the denominator 2. Whole number 9 equally 9 * 2/2

= 18/2

b) Add the answer from previous step 18 to the numerator 1. New numerator is 18 + 1 = 19

c) Write a previous answer (new numerator 19) over the denominator 2.

Nine and one half is nineteen halves

Conversion a mixed number 19 1/4

to a improper fraction: 19 1/4 = 19 1/4

= 19 · 4 + 1/4

= 76 + 1/4

= 77/4

To find new numerator:

a) Multiply the whole number 19 by the denominator 4. Whole number 19 equally 19 * 4/4

= 76/4

b) Add the answer from previous step 76 to the numerator 1. New numerator is 76 + 1 = 77

c) Write a previous answer (new numerator 77) over the denominator 4.

Nineteen and one quarter is seventy-seven quarters

Multiple: 19/2

* 77/4

= 19 · 77/2.4

= 1463/8
