Multiply: 5/12 x 4/9 =

To multiply mixed numbers 3and 2​, first convert each mixed number to an improper fraction.

Convert 3and 2​​ to improper fractions:

3= 3 + = =

2​ = 2 + ==

Next, multiply the two improper fractions:

​ ×

=

To reduce​ to its lowest terms, we find the greatest common divisor (gcd) of 385 and 55. Both 385 and 55 are divisible by 55:

= 385÷55 ​= 7

The correct answer is: A 7

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 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

To determine which option represents the largest amount, consider the values in a comparable format:

A. 73.9% (equivalent to 0.739)

B. 16.25 (a whole number, clearly more than any of the percentages if you consider their decimal forms)

C. 95% (equivalent to 0.95, which is the largest among the percentages)

D. 1.25% (equivalent to 0.0125)

B 16.25 is clearly the largest number here, as it surpasses all the percentages when converted into decimal or whole number forms.
