she had a perfect score in 1/8 of all tests
she had a perfect score in 4 tests
Step-by-step explanation:
Tamara earned an A in 5/8 of all the tests she took.
In 1/5 of the those tests she got an A, she had a perfect score.
1/5 of 5/8 is 1/5 * 5/8 which equals 5/40 which can be reduced to 1/8.
That means that in 1/8 of all tests she took she got a perfect score.
She took a total of 32 spelling tests.
1/8 of 32 = 1/8 * 32 = 32/8 = 4
she had a perfect score in 1/8 of all tests
she had a perfect score in 4 tests
