5. Mary’s father harvested 2 150 mangoes on Monday and 2 350 on Tuesday.
He divided the mangoes among his 10 children. How many mangoes did
each child get?
Answer:
Step-by-step explanation:
1. 12 567 seats – 120 not occupied = seats were occupied
2. dress originally costs P 980.00 x 35% = 343
new price = 980 – 343 = P 637
3. 4cm x 1m / 100m = 0.04m
10 m / 0.04m = 2500 m
4. 3/4 kg of corn bits
repacked this into 1/8 kg
3/4 divide 1/8 = 24/4 = 6/1 or 6 packs
5. 2 150 mangoes on Monday
2 350 on Tuesday
2150+2350 = 4500/10 = 450 mangoes did each child
