Answer:
a 4 1/5
b 7 7/24
Step-by-step explanation:
a 7/9 * 5 2/5
Change the mixed number to an improper fraction
7/9 * (5*5+2)/5
7/9 * 27/5
Rewrite
7/5 * 27/9
7/5 * 3
21/5
Change this back to a mixed number
5 goes into 21 4 times (4*5 = 20 ) with 1 left over
4 1/5
b 1 3/4 * 4 1/6
Change to improper fractions
(4*1+3)/4 * (6*4+1)/6
7/4 * 25/6
175/24
Change back to a mixed number
24 goes into 175 7 times (7*24 =168 ) with 7 left over
7 7/24
Answer:
![10 \frac{9}{25}](https://tex.z-dn.net/?f=10%20%5Cfrac%7B9%7D%7B25%7D%20)
Step-by-step explanation:
![\bigg( \frac{3}{5} \bigg)^{2} + 4 \times 3 - 2 \\ \\ = \frac{9}{25} + 12 - 2 \\ \\ = \frac{9}{25} + 10 \\ \\ = \frac{9 + 10 \times 25}{25} \\ \\ = \frac{9 + 250}{25} \\ \\ = \frac{259}{25} \\ \\ = 10 \frac{9}{25}](https://tex.z-dn.net/?f=%20%5Cbigg%28%20%20%5Cfrac%7B3%7D%7B5%7D%20%5Cbigg%29%5E%7B2%7D%20%20%2B%204%20%5Ctimes%203%20-%202%20%5C%5C%20%20%5C%5C%20%20%3D%20%20%5Cfrac%7B9%7D%7B25%7D%20%20%2B%2012%20-%202%20%5C%5C%20%20%5C%5C%20%20%3D%20%20%5Cfrac%7B9%7D%7B25%7D%20%20%2B%2010%20%5C%5C%20%20%5C%5C%20%20%3D%20%20%5Cfrac%7B9%20%2B%2010%20%5Ctimes%2025%7D%7B25%7D%20%20%5C%5C%20%20%5C%5C%20%20%3D%20%20%5Cfrac%7B9%20%2B%20250%7D%7B25%7D%20%20%5C%5C%20%20%5C%5C%20%20%3D%20%20%5Cfrac%7B259%7D%7B25%7D%20%20%5C%5C%20%20%5C%5C%20%20%3D%2010%20%5Cfrac%7B9%7D%7B25%7D%20)
