2 x 45 = 90
Two times forty-five gives you ninety. Because 45 + 45 equals 90.
45 can go into 90 exactly 2 times. This is because when you divide 90 by 45, you get a quotient of 2 with no remainder. In other words, 45 can fit into 90 two times evenly.
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.
The answer is 200% because 100% of 45=45 and 90 is two times 45 therefore it is 200%.
90 is 45 percent of 200 because 200 times 0.45 = 90.
90% of 45= 90% * 45= 0.9 * 45= 40.5
45 times 19 gives you 855.
