Answer:
1.)
5/7 bangus = 72.50 pesos
72.50 ÷ 5/7 = 203/2 or 101.5
101.5 per kilo
203/2 ×2/7 =29
2/7 bangus = 29 pesos
29 + 72.50 = 101.5 pesos
101.5 × 2 1/7 kilo = 203/2 ×15/7 = 3045/14
= 217.5 pesos
2.) 4/9 + 3/10 = 67/90
7500 × 67/90 = 5583 1/3
7500 - 5583 1/3 = 1916 2/3
1916 2/3 ÷ 2 = 958 1/3 pesos each sack of rice.
3.) 9/9 - 2/9 = 7/9
7/9 × 3/7 = 21/63 or 3/9
7/9 - 3/9 = 4/9
36 ÷ 4/9 = 81 total followers
81 × 2/9 = 169/9 or 18 roses
81 × 3/9 = 243/9 or 27 sunflowers
81 × 4/9 = 324/9 or 36 tulips
18 roses + 27 sunflowers = 45 flowers
4.) 2 + 3 + 2/4 + 3/4
= 5 + 5/4
= 25/4 or 6 1/4
5.) 3 1/2 - 2 1/3
= (3 - 2) + (1/2 - 1/3)
=11/6
