15 of the flowers in a flower shop were lilies,
12 of them were peonies and the remaining 30 stalks were tulips.
- 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 tulips
= 1 -
15 -
12 = 1 -
210 -
510 = 1 -
710 =
310 3 u = 30
1 u = 30 ÷ 3 = 10
Number of stalks of flowers in the shop
= 10 u
= 10 x 10
= 100
(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 = 100
2 p = 100 - 6
2 p = 94
1 p = 94 ÷ 2 = 47
Number of stalks of flowers sold
= 1 p + 6
= 47 + 6
= 53
Answer(s): (a) 100; (b) 53
