the LCD of the two is 9 what you do is this so 1/3,2/9 is simple its 1/3 2/3 1 then lets try the 2/9 2/9 4/9 6/9 and keep doing that until they both reach the SAME number.
The answer to that is 1448
Answer:
2/10
Step-by-step explanation:
Ms. Geiger made 100 cupcakes.
a) Number of chocolate
60/100 were chocolate
= 60/100 × 100 = 60 chocolate cup cakes
b) Number of vanilla
2/10 were vanilla
Hence:
2/10 × 100 = 20 vanilla cup cakes
c) the rest were red velvet.
Number rod red velvet = 100 - (60 + 20)
= 100 - 80
= 20 velvet cupcakes
What fraction of the cupcakes were red velvet?
Converting to fraction
Number of velvet cupcakes/Total number of cakes
= 20/100
= 2/10
Answer:
Step-by-step explanation:
5 x + 10 y = 15 (1)
10 x + 3 y = 13
We want to use the linear combination method and addition to eliminate the x-terms, so we want in the equation (1), there will be the term -10x. Then, we have to multiple both side of (1) by -2.
And we have
-10 x - 20 y = - 30
10 x + 3 y = 13
------------------- (add)
0 - 17y = -17
or y = 1 and x = 1
