Answer:
-6 314/405
Explanation:
( -2 1/3)^3 / (1 7/8)
I am going to change the mixed numbers to improper fractions
2 1/3 = (3*2 +1)/3 = 7/3
1 7/8 = (8*1+7)/8 = 15/8
( -7/3)^3 / (15/8)
I will use copy dot flip
( -7/3)^3 * (8/15)
Now I can split the first term into parts (a/b)^x = a^x/ b^x
(-7)^3/ 3^3 *8/15
-343/27 * 8/15
-2744/405
Now we need to change it back to a mixed number
405 goes into 2744 6 times
6*405 =2430 2744-2430 = 314
-6 314/405
