First, we need to convert the mixed numbers to improper fractions:
3 1/2 = 7/2
1 3/4 = 7/4
Next, we multiply the numerators together and the denominators together:
(7/2) x (7/4) = (7 x 7) / (2 x 4) = 49/8 Therefore, Greg now has 49/8 grains of rice. We can simplify this fraction by dividing both the numerator and denominator by their greatest common factor, which is 1: 49/8 = 6 1/8
So, Greg now has 6 1/8grains
