• Make equivalent fractions with denominator over 100
• Find a percentage of a number
• Convert fractions and decimals greater than 100% to decimals.

Q1)

= 16cm^2

It's a square all sides are the same and finding the area times both sides.

Q2)

The area is 9^2 = 81

It's a square meaning all sides are the same.

So two SAME numbers that times together to make 81

9cm

Square root 49 and 64 to get the number that you square to get it.

$${\mathtt{5\,185}}{\mathtt{\,\times\,}}{\mathtt{0.7}} = {\frac{{\mathtt{7\,259}}}{{\mathtt{2}}}} = {\mathtt{3\,629.5}}$$

£34.29

If both sides of a square is 8cm then the area is 64cm

8*8

If the total is 25cm^2 = 625

Each side is 25 

25*25

I understand those two sentence.

So the total is 1865^2

( I probably would've never thought of this, but i have already seen your post)

To find a near middle of 1865 find the sqrt of it and round it then take it away from 1865^2 . The smaller one would be the smaller portrait.

If they were the same wouldn't the answer be ( JUST FOR QUEEN , IF THERE WAS NO KING) 1865

=1865^2

1865*1865

Thank you Melody, I see my mistake.

Okay :)

30 fits into 43 once

remaining 13

30 denominator

1 + 13/30

Lol.

There are 12 inches in a foot.

Find a Common Denominator.

5, 9, 15

5*9= 45

9*5=45

15*3=45

45 is a Common Denominator.

1/5   =    5*9 .   So do the same to the numerator   1*9 =9

9/45

-----------------

5/9    =   9*5=4 . So do the same do the numerator.      5*5=25

25/45

------------------

2/15    =     15*3.     So do the same to the numerator.     2*3  = 6

9/45+ 25/45 + 6/25

$${\frac{\left({\mathtt{9}}{\mathtt{\,\small\textbf+\,}}{\mathtt{25}}{\mathtt{\,\small\textbf+\,}}{\mathtt{6}}\right)}{{\mathtt{45}}}}$$

= 40

40/45  = 8/9 (Simplified)

8/9
