Rounding is simple:
- If the previous digit is 5-9, round the number to the left of it up a number. If it is 4-0, leave the number to the left of it as it is.
For 82.98, we can round 82 to 83, since 82 is the whole number and the previous digit is 9 (so we round up).
For 169.645, we scratch off 45. Since 6 is in the tenth's place and the previous digit of it is 4, we leave it at 169.64.

Answer:
Step-by-step explanation:
On the day of the canteen, 800 coupons were sold, the price of each coupon was RM 30 and RM 50 respectively. The amount of money earned from the sale of coupons was RM30000. How many copies of RM30 and RM50 coupons were sold?
Let:
RM 30 = x
RM 50 = y
x + y = 800 - - - (1)
30x + 50y = 30000 - - - (2)
From (1)
x = 800 - y
Put x = 800 - y in (2)
30(800 - y) + 50y = 30000
24000 - 30y + 50y = 30000
24000 + 20y = 30000
20y = 30000 - 24000
20y = 6000
y =
62,810 rounded up is 60,00
The answer to (-5)-3 is -8. I may be wrong but I did the work.
