Iwould really appreciate it if someone could answer these as i'm really stuc and its due for tomorrow.
1. estimate the value of 50.75 x 0.18
2. estimate the value of 96 divided by 0.499
3. by rounding each number to one significant figure, estimate the answers to:
1. 8.2 x 6.7

0.46
2. 23.4 x 13.9

0.18

1. Round 50.75 to 50 and 0.18 to 0.20.
50 x 0.2 = 10

2) Round 96 to 100 and 0.499 to 0.5
100 divided by 0.5 = 50

3a) Round 8.2 to 8, 6.7 to 7, and 0.46 to 0.50
8 x 7 divided by 0.50 = 112

3b) Round 23.4 to 20, 13.9 to 10, and 0.18 to 0.20
20 x 10 divided by 0.20 = 2,000

396cm

Step-by-step explanation:

55 x 40 = 2,200

2,200 x 180 = 396,000

396,000 / 1000 = 396

396cm

(I don't know for sure).
