Answer:
Tammy is incorrect
Step-by-step explanation:
The product of 5/7 and 1 1/4 is,
(5/7) x (1 1/4)
turn the mixed number to a whole number.
1 1/4= 4/4 + 1/4 = 5/4
(5/7) x (5/4) = 25/28 which is approximately 0.8929
Tammy believes it equals 1 3/4
1 3/4 = 4/4 + 3/4 = 7/4 which is 1.75
0.8929 does not equal 1.75
