19 of the flowers in a flower shop were roses,
12 of them were poppies and the remaining 91 stalks were lilies.
- How many stalks of flowers were there in the shop?
- At the end of the day, the number of flowers left was 6 less than the number of flowers sold. How many stalks of flowers were sold?
(a)
Fraction of stalks of flowers that were lilies
= 1 -
19 -
12 = 1 -
218 -
918 = 1 -
1118 =
718 7 u = 91
1 u = 91 ÷ 7 = 13
Number of stalks of flowers in the shop
= 18 u
= 18 x 13
= 234
(b)
Number of stalks of flowers sold = 1 p + 6
Number of stalks of flowers left = 1 p
Total number of stalks of flowers
= 1 p + 1 p + 6
= 2 p + 6
2 p + 6 = 234
2 p = 234 - 6
2 p = 228
1 p = 228 ÷ 2 = 114
Number of stalks of flowers sold
= 1 p + 6
= 114 + 6
= 120
Answer(s): (a) 234; (b) 120
