How to multiply 2 1 /2 multiply 1/10

Answers

Answer 1
Answer:

Okay, this will be simple.

Notice that 2 1/2 is a mixed number. This needs to be changed to an IMPROPER FRACTION.

To do this, multiply the denominator by the whole number

2 x 2 = 4

Add numerator and keep denominator the same.

5/2.

Okay, so 5/2 x 1/10.

When multiplying fractions, no common denominator is needed. Just multiply the numerators and denominators.

5 x 1 = 5

2 x 10 = 20.

5/20 which reduces to 1/4. (5 is the GCF of 5 and 20, 5 divided by 5 = 1 and 20 divided by 5 = 4)

5/20 or 1/4 is your answer. (they mean the same thing)

To find the circumference of the semicircle, first multiply the diameter, 2, by pi, or 3.14. 2*3.14 = 6.28. This is the circumference of the hypothetical full circle, which we must divide by 2 because it is a semicircle! So the circumference is 3.14. Now, find the perimeter of the rectangular portion, which is 5+5+2 = 12. Now, add.
3.14 + 12 = 15.14.
The answer is d. 15.14 ft.

When measuring distance 12 beads are approximately equal to 6 erasers. how many erasers are equal to 18 beads? How many beads are equal to 42 erasers?

Well, since 12 divided by 6 would equal 2. So 9 erasers would equal to 18 beads (18 ÷ 2). 21 beads equal 42 erasers.

Which equation does not belong with the other three:5y=2x

y=2 fifths x

10y=4x

5xy=2

Answers

5xy = 2 does not belong, because it doesn't simplify to 5y = 2x like the others. The second one is done when you divide both sides by 5, and you get y = 2/5x, which is true. The third one is done when you multiply both sides by 2, which is 10y = 4x, which is also true. But for the fourth one, to get x to move, you need to divide x from both sides, which is NOT 5xy = 2, it's actually 5y/x = 2. Hope this helps :D
