Hazel gave 2/7 of her stickers to Benny and 1/3 to them to Julie.

Firstly, make the denominator the SAME.
COMMON MULTIPLE of 3 and 7 is 21.
Multiple of 3: 3, 6, 9, 12, 15, 18, 21, 24...
Multiple of 7: 7, 14, 21, 28....

Therefore,
2/7 to Benny ------> 6/21 ------> 6units
1/3 to Julie ---------> 7/21 ------> 7units
Since Julie received 10more stickers than Benny,
7/21 - 6/21 = 1/21
1/21 -----------------> 1unit = 10stickers

6 X 10 = 60Stickers

Hope it helps!
