What is

plus

Step-by-step explanation:

2/4 + 3/5

LCM = 20

2/4 = 2*5/4*5 = 10/20

3/5 = 3*4/5*4 = 12/20

2/4 + 3/5 = 10/20 + 12/20   = 22/20

24+35= 1 1/10

Solution with Steps

24+35=?

The fractions have unlike denominators. First, find the Least Common Denominator and rewrite the fractions with the common denominator.

LCD(2/4, 3/5) = 20

Multiply both the numerator and denominator of each fraction by the number that makes its denominator equal the LCD. This is basically multiplying each fraction by 1.

(24×55)+(35×44)=?

Complete the multiplication and the equation becomes

1020+1220=?

The two fractions now have like denominators so you can add the numerators.

Then:

10+1220=2220

This fraction can be reduced by dividing both the numerator and denominator by the Greatest Common Factor of 22 and 20 using

GCF(22,20) = 2

22÷220÷2= 1 1/10

The fraction

1 1/10

is the same as

11÷10

Convert to a mixed number using

long division for 11 ÷ 10 = 1R1, so

1 1/10

Therefore:

24+35=1 1/10

- "runner b is moving at a slower rate."

- "the graphs shown are graphs of distance(km) against time(min).

the slopes of this graphs are are given by:

slope = (change in y)/(change in x)

= (change in distance)/(change in time)

this is the formula for finding the speed. so, the slope of these graphs represent the speed of the runner.

taking each division in the graph to represent 1 on both axis:

runner a ⇒ speed = (2-0)/(1-0)

= 2/1

= 2 km/min

runner b ⇒ speed = (3-0)/(3-0)

= 3/3

= 1 km/min

this shows that   runner b is moving at a slower rate."

all group life insurance is term insurance. actually it is annual renewable term and it is rated on the average age and claims experience of the entire group, which is called "experience rating." remember, this type of insurance has a 31-day grace period and is convertible to whole life upon leaving employment. a contributory group plan requires that both the employer and the employees pay part of the premium. at least 75% of those eligible must participate, so the group is sure to get most of the healthy employees as well as those that are sick.
