15 of the flowers in a flower shop were daisies,
12 of them were poppies and the remaining 51 stalks were peonies.
- How many stalks of flowers were there in the shop?
- At the end of the day, the number of flowers sold was 8 more than the number of flowers left. How many stalks of flowers were sold?
(a)
Fraction of stalks of flowers that were peonies
= 1 -
15 -
12 = 1 -
210 -
510 =
310 3 u = 51
1 u = 51 ÷ 3 = 17
Number of stalks of flowers in the shop
= 10 u
= 10 x 17
= 170
(b)
Number of stalks of flowers sold = 1 p + 8
Number of stalks of flowers left = 1 p
Total number of stalks of flowers
= 1 p + 1 p + 8
= 2 p + 8
2 p + 8 = 170
2 p = 170 - 8
2 p = 162
1 p = 162 ÷ 2 = 81
Number of stalks of flowers sold
= 1 p + 8
= 81 + 8
= 89
Answer(s): (a) 170; (b) 89
