Answer:
0.8 OR ![\frac{4}{5}](https://tex.z-dn.net/?f=%5Cfrac%7B4%7D%7B5%7D)
Step-by-step explanation:
The reciprocal of any number is the number that it multiplies by to equal 1.
The reciprocal can be found by simply converting the number into a fraction and then 'flipping' the fraction as any number multiplied by its reciprocal is 1.
E.g.
No. X/Y * Y/X (its reciprocal) = 1
![\frac{x}{y} *\frac{y}{x} =\frac{xy}{xy} =1](https://tex.z-dn.net/?f=%5Cfrac%7Bx%7D%7By%7D%20%2A%5Cfrac%7By%7D%7Bx%7D%20%3D%5Cfrac%7Bxy%7D%7Bxy%7D%20%3D1)
So, to find the reciprocal of 1.25,we should first convert 1.25 to a fraction.
1.25 = 125/100
![\frac{125/25}{100/25}=\frac{5}{4}](https://tex.z-dn.net/?f=%5Cfrac%7B125%2F25%7D%7B100%2F25%7D%3D%5Cfrac%7B5%7D%7B4%7D)
Now we just flip 5/4 to get our reciprocal:
= 0.8
Test: 0.8 * 1.25 = 1
The reciprocal of 1.25 (
) is 0.8 (
).
Hope this helped!
I think its b because it makes sense

Step-by-step explanation:
Answer:
A
Step-by-step explanation:
Answer:
3) 162 ft² || 4) 38.25 mm²
Step-by-step explanation:
3)
area of triangle = 0.5 * base * height
= 0.5 * 27 * 12
= 162 ft²
4) area of triangle = 0.5 * base * height
= 0.5 * 8.5 * 9
= 38.25 mm²
