Seven girls each have seven cats. How many legs are there in the group?

To convert 0.26 to a fraction, you first recognize it as​ because 0.26 is 26 hundredths.

Next, to simplify​, you find the greatest common divisor of 26 and 100. Both numbers are divisible by 2, so:

=

Checking the options:

• A: 26/10026/100 (correct but not in simplest form)
• B: 7/87/8 (irrelevant)
• C: 26/1026/10 (incorrect form)
• D: 13/5013/50 (correct and in simplest form)

Answer: D 13/50

To calculate the total number of legs in the group, we need to consider both the legs of the girls and the legs of the cats.

Each girl has 2 legs. Since there are 7 girls:

7×2=14legsfromthegirls

Each cat has 4 legs. Since each girl has 7 cats, there are a total of:

7×7=49cats.

Thus, the total number of legs for the cats is:

49×4=196legsfromthecats.

Adding the number of legs from the girls and the cats gives:

14+196=210legsintotal

The correct answer is B 210.

To find average items to be sold per day, divide the total items to sell by number of selling days remaining.

Averageitemsperday=TotalitemstosellNumberofsellingdays

Substitute the given numbers into the formula:

Items to sell – 63

Number of selling days – 18

Averageitemsperday=

Now, perform the division:

Averageitemsperday=3.5

Since all the items are not in fraction, round up to the next whole number.

Thus, the salesman needs to sell an average of 4 items per day.

The correct answer is: B 4

To add ​ and ​, first convert ​ to an improper fraction:

= =

Now add ​ and ​. To do so, find a common denominator, which for 3 and 7 is 21:

= =​

= = ​

Add these fractions:

+ ​= = ​

Since ​ is an improper fraction, convert it to a mixed number:

47 ÷ 21 = ​

Thus, the correct answer is: C 2 5/21
