Hi Lexi!

Find Common Denominators:

3 1/4 = 3 3/12

2 5/6 = 2 10/12

1 3/4 = 1 9/12

Add Wholes:

3 + 2 + 1 = 6

Add Fractions:

3/12 + 10/12 + 9/12 = 22/12 = 1 10/12

Add both:

6 + 1 10/12 = 7 10/12

Simplify:

7 10/12 = 7 5/6

Answer:

7 5/6

Hope This Helps :)

How would you calculate the area and perimeter of 3yd 6yd 5yd 10yds

spayn [35]

Okay, start with the smaller square, you know the side length is 3 and that the width is 5, multiply this together:
3 * 5 = 15

That's the smaller left side of this shape, now the bigger side, divide the 10 yards at the bottom by 2 to properly represent the other side then multiply this by the 6 over there.
5 * 6 = 30

Conclusion for Area: After adding the results the answer should be 45.

The perimeter is solely adding all the sides together. You have a 10, two 5's, one 6, and two 3's. Add this together:

10 + 5 + 5 + 6 + 3 + 3 = 32

Conclusion for Perimeter: So the perimeter would be 32.

I hope this helps in someway, have a great rest of your day! ^ ^

There are 72 boys and 90 girls on the math team for the next math competition Mr. Johnson would like to arrange all the students

yawa3891 [41]

Answer:

Mr. Johnson can arrange 18 students in each row, that is 4 rows of boys and 5 rows of girls.

Step-by-step explanation:

Given:

Number of boys = 72

number of girls = 90

We need to arrange students in rows with equal number of only boys and only girls.

To find the maximum number (x) of boys or girls in each row, we will find the GCF (Greatest Common Factor) of the numbers 72 and 90, such that 'x' divides both numbers evenly without a remainder.

Now to find GCF we will factorize both numbers.

$72 = 2\times2\times2\times3\times3$
