Answer:
A. 270
Step-by-step explanation:
30% can be rewritten as 3/10
To multiply 900 by 3/10, just divide by 10 (90) and multiply by 3 (270)
Therefore, the answer is A. 270
Bonus: To find the actual price, just subtract this amount (270) from the original price (900).
The television costs $630.
According to given figure, The Triangle BDC is a right angled Triangle (Angle D = 90°)
So, we can apply Pythagoras theorem to find the Side a (Hypotenuse)
Now, let's solve ~
Therefore, Length of side a is 5 units ~
7/10 of 80 is 56
4/5 of 80 is 64
3/4 of 80 is 60
5/8 of 80 is 50
1/2 of 80 is 40
1/4 of 80 is 20
1/10 of 80 is 8
1/8 of 80 is 10
to work these out divide the number by the denominator (bottom number) and multiply by the numerator (top number)
