Answer:
13
Step-by-step explanation:
We want to multiply 6 8/9 * 1 9/10. First, we need to transform the mixed numbers into improper fractions:
6 8/9 = (9*6 + 8)/9 = 62/9
1 9/10 = (1*10 + 9)/10 = 19/10
And now we have to multiply each numerator and each denominator, as follows:
62/9 * 19/10 = (62*19)/(9*10) = 1178/90 ≈ 13
