Because the majority is in decimal form, you'll have to change the fraction to a decimal too so that it would be easier to solve this problem. 4/5 in decimal form is 0.8
So, the order from least to greatest is
0.6, 0.75, 4/5
Hope this helps :)
If you mean 749 x 9 the answer is 6,660
Answer:
42:21 as a ratio
Step-by-step explanation:
The way you would make this a ratio was to make inches to inches so it would be 42:21.
Area of right-angled triangle is given by;
Area, A = 1/2 *b*h, Where b=base, h=height
Therefore,
A1 = 1/2bh = 16 in^2
A2 = 1/2 (2b)(2h) = 2bh
Ratio of increase = A2/A1 = {2bh}/(1/2bh} = 4 (the area is increased 4 times)
The,
A2 = 4*16 = 64 in^2
Therefore,
The area is increased by (64-16) = 48 in^2
