Solve the proportion ( find the value of X): 9:14 :: X:56 A. X= 14 B. X = 25 C. X = 36 D. X = 42

The first step to solving a proportion problem is to rewrite the problem as a fraction. 9 = X 14 56 then you cross multiply and solve the resulting equation. 14X = (9)(56) 14 X = 504 X =504/14 remember 14X/14 and 504/14 14 on both sides of the equation X = 36

How many millimeters are there in 5 meters. A. 500 B. 5,000 C. 50,000 D. 500.00

The prefix *milli- means 1,000. There are 1,000 millimeters in 1 meter, so there are 5,000 millimeters in 5 meters. Alternatively, use dimensional analysis to convert ( 5 meters) * 100 cm * 10 mm = 5000 cm 1 meter 1 cm * 1 Kilometer = 1,000 Meters * 1 Meter = 100 Centimeters * 1 Centimeter = 10 Millimeters

multiply: (0.67)(0.09) = A. 0.000603 B. 0.006030 C. 0.060300 D. 0.603000

The product of two decimal will always have the same number of decimal places as the sum of the number of decimal places that the multiplicand and the multiplier have. (67)(9) = 603. The multiplicand is .67 and has 2 decimal places. The multiplier is .09 and has 2 decimal places. Therefore, our answer is .0603. Don't get tripped up by the extra zeros. Zeros before our answer and after the decimal point increase the number of decimal places. Zeros after our answer and after the decimal point do not increase the number of decimal places. Answer: C 0.67 X 0.09 0603 000 000 0.060300
