It is: 500*90 = 45000
the answer to that would be 6*90
To find 90% of 40, just multiply .90 times 40, which equals 36. Since 10% of 40 is 4, then 90% of 40 are 4*9=36.
To estimate (90 \times 0.4), you can round (0.4) to a simpler value. Since (0.4) is close to (0.5), you can estimate (90 \times 0.5), which equals (45). Thus, the estimate for (90 \times 0.4) would be slightly less than (45), around (36). A quick calculation gives (90 \times 0.4 = 36), confirming the estimate.
90 feet is 27.43 meters.
20 x 90 = 180020 times 90 equals 18 times 100 equals 1800.
3*30=90
2.5*36 = 90
It equals: 7,200
90 x 90 = 8,100
15 times 90 equals 1350.

24 x 3.75 = 90
725 multiplied by 90 equals 65,250.
It is: 500*90 = 45000
0.4 x 90 = 36
6 x 15 = 90
