Question

with explanation pls i dont understand

Answer 1

Answer:

Conversion a mixed number 3 3/

4

to a improper fraction: 3 3/4 = 3 3/

4

= 3 · 4 + 3/

4

= 12 + 3/

4

= 15/

4

To find a new numerator:

a) Multiply the whole number 3 by the denominator 4. Whole number 3 equally 3 * 4/

4

= 12/

4

b) Add the answer from previous step 12 to the numerator 3. New numerator is 12 + 3 = 15

c) Write a previous answer (new numerator 15) over the denominator 4.

Three and three quarters is fifteen quarters

Answer 2

Step-by-step explanation:

Add the whole numbers first.

$\sf\blue{\implies 5+\dfrac{4}{3}+\dfrac{3}{5}}$

Find the Least Common Denominator (LCD) of $\sf\dfrac{4}{3},\dfrac{3}{5}$ In other words, find the Least Common Multiple (LCM) of 3,5.

LCD = 15

Make the denominators the same as the LCD.

$\sf\implies 5+\dfrac{4\times 5}{3\times 5}+\dfrac{3\times 3}{5\times 3}$

Simplify. Denominators are now the same.

$\sf\implies5+\dfrac{20}{15}+\dfrac{9}{15}$

$\tt \implies5 + \dfrac{29}{15}$

Convert $\tt\dfrac{29}{15}$ to mixed fraction.

$\sf5+1\dfrac{14}{15}$

$\red{\boxed{ \boxed{\boxed{ \boxed{\boxed{ \boxed{ \tt \implies6 \dfrac{14}{15} }}}}}}}$
