Answer 1

Д)16 2\3*1 1\5= 50/3 * 6/5 = 20

2 3\4*3 1\3=15/4 * 10/3 = 25/2=12 1/2

Answer 2

д) 16 2/3 * 1 1/5 =

First, we need to convert the mixed numbers to improper fractions:

16 2/3 = (16*3 + 2)/3 = 50/3

1 1/5 = (1*5 + 1)/5 = 6/5

Now we can multiply the fractions:

(50/3) * (6/5) = (506)/(35) = 300/15 = 20

So, 16 2/3 * 1 1/5 = 20.

2 3/4 * 3 1/3 =

Again, we need to convert the mixed numbers to improper fractions:

2 3/4 = (2*4 + 3)/4 = 11/4

3 1/3 = (3*3 + 1)/3 = 10/3

Now we can multiply the fractions:

(11/4) * (10/3) = (1110)/(43) = 110/12

We can simplify this fraction by dividing both the numerator and denominator by their greatest common factor, which is 2:

110/12 = (255)/(26) = 55/6

So, 2 3/4 * 3 1/3 = 55/6.
