tyler bought 7/6 meters of ribbon. she needs 2/5 meters to warp her brother's peresnt and 3/4 meters to warp her sister's present. DID SHE HAVE ENOUGH?
Well... she needs 2/5 +3/4 = 8/20 + 15/20 = 23/20 to do her jobs.
IS 7/6 greater than or equal to her needs of 23/20 ???
7/6 = 70/ 60 >= ? 23/20 ?
70/60 >= 69/60 Yep ....she has just barely enough!
