Explain it - compare 3 3/22 & 3 2/33. which is greaterI Know:
Multiply the denominator by the whole number then add numerator to that.
Now I have 69/66 & 101/99

THe LCM is 66

what next, which is greater. Thank you

Answers

3 3/22 isn't 69/66.
3 3/22 is like 3+3/22. To sum them,you have to have the same denominator. So 3=66/22. Know you can add them, so 3 3/22=3+ 3/22= 66/22+3/22=69/22.
Same way, 3 2/33= 3+2/33=99/33+2/33=101/33.
Know you have to compare 69/22 with 101/33. For this, you need to get them to the same denominator. So you multiply 69/22 with 3, and 101/33 with 2. Know you have to compare 207/66 with 202/66. Obviously, the first one is bigger, because 207>202. So in the end, 3 3/22> 3 2/33

A square has side length 6 inches. A parallelogram has a base of 6 inches. The area of the square is equal to the area of the parallelogram. What is the height of the parallelogram? How do i solve this?

Answers

The area of a parallelogram is base x height thus height will be 6 inches.

What is a parallelogram?

A parallelogram's facing or opposing sides are of equal length, and its opposing angles are of similar size.

A basic quadrilateral with two sets of parallel sides is known as a parallelogram.

There are 4 types of parallelograms, including 3 special types. The four types are parallelograms, squares, rectangles, and rhombuses.

As per the given,

Area of square = 6 x 6 = 36

Area of parallelogram = 6 x height

Height x 6 = 6 x 6

Height = 6

Hence " The area of a parallelogram is base x height thus height will be 6 inches".
