For the multiplication ones, make them mixed numbers.
7/3 times 7/2. Multiply tops and bottoms. 49/6. 8 1/6.
22/5 times 3/1 66/5 or 13 1/5.
35/6 times 14/5. 490/30. 16 1/3.
Estimate: 9 5/6 becomes 10 and 2 1/8 becomes 2. 10/2 is 5.
A recipl is when you flip the fraction, so 5/2.

1) 2 1/3 = 7/3 and 3 1/2 = 7/2 so the answer for this is 7/3
2) 4 2/5 = 22/5 * 3 = 66/5
3) 5 5/6 = 35/6 amd 2 4/5 = 14/5 so 35/6 * 14/5 = 490/30 or 49/3
4) 9 5/6 = 54/6 and 2 1/8 = 11/8 so 56/6 divided by 11/8 is the same as 56/6 * 8 /11 = 454/66 or 227/33
5) The recipricol is the same as taking 1/2/5 which is 5/2

first change the mixed numbers to improper fractions and then multiply the fractions.
2 1/3 = 7/3 mult denomination (3) by integer portion (2) and add the numerator (1) to get the 7, then put over denominator of mixed number (3)
3 1/2 = 7/2
7/2 * 7/2 = 49/4
4 2/5 = 22/5 * 3/1 = 66/5
5 5/6 = 35/6; 2 4/5 = 14/5
35/6 * 14/5 = first reduce to 7/3 * 7/1 and get
49/3
estimate 10 / 2 = 5 (round to nearest whole number!)
reciprocal of 2/5 is 5/2 (flip it - or in other terms make denominator the numberator and vice versa

7/3 x7/2=49/6= 8 1/6
22/5 x 3/1= 66/5=13 1/5
35/6 x 14/5=49/3=16 1/3
10 / 17/8=10/1 x 8/17=80/17= 4 12/17
5/2 is recirocal of 2/5
