(a)
The total number of muffins remains unchanged. Make the total number of muffins the same. LCM of 4 and 5 is 20.
Number of muffins baked by Jen
= 8 u - 5 u
= 3 u
Number of muffins baked by Tina and Paul
= 12 u + 5 u
= 17 u
Total number of tarts = 20 u
Fraction of the muffins baked by Tina and Paul =
1720(b)
Total number of muffins baked by Tina and Paul = 17 u
17 u = 391
1 u = 391 ÷ 17 = 23
Total number of muffins the three girls baked
= 20 u
= 20 x 23
= 460
Answer(s): (a)
1720; (b) 460
