Please, use ( ) around fractional coefficients:
<span>1/3x-9y, 6/5x-15y should (probably) be written as (1/3) - 9y and (6/5)x - 15 y.
The LCD here is 3(5) = 15.
Mult. </span><span>1/3x-9y and 6/5x-15y by 15, and then divide the result by 15:
</span>15 [ (1/3)x - 9y and (6/5)x - 15 y ]
---------------------------------------------
15
This simplifies to:
5x - 135y and 18x - 225y
------------ --------------
15 15
These fractions are equivalent to the original ones, but now the common denominator, 15, is evident.
Answer:
9/24
Step-by-step explanation:
3/8
24 ÷ 8 = 3
3 x 3 = 9
9/24
Check:
9/24 = 0.375
3/8 = 0.375
Answer:
The table C
Step-by-step explanation:
when you multiply the x number in the table c by 0.3 you get the same answer as the one in the y column. The constant of proportionality is the value that stays constant in the ratio. Since when you multiply each number in the x column by 0.3 and you always get the number in the y column it shows that the table c is correct.
Answer:
3/4
Step-by-step explanation:
The zero at the end of the number is not important, so you are left with 0.75
Basically, you can think of it as 75 is three-fourths of 100, so the fraction would be 3/4. (and 3/4 is completely simplified)
