is there an option for no solution? because when I solved there were no possible rational solutions
Step-by-step explanation:
To convert 0.45 to percent multiply by 100
<span>0.45 × 100 = </span>45 %
<span>Write the decimal number as a fraction
(over 1)
0.45 = 0.45 / 1
Multiplying by 1 to eliminate 2 decimal places
we multiply top and bottom by 2 10's
Numerator (N)
N = 0.45 × 10 × 10 = 45
Denominator (D)
D = 1 × 10 × 10 = 100
N / D = 45 / 100
Simplifying our fraction
= 45/100
= 9/20

The answer is 4, A composite number has more than 3 factors for it and 4 has 1,2,4. Hope this helps
Answer:
23/60
Step-by-step explanation:
All fractions of tiles, when summed up, need to be 1
Indian red is 1/4 of the tiles
Tuscan blue is 1/6 of the tiles
Fucalyptus is 1/5 of the tiles
Sand is X of the tiles (X is the fraction we want to know)
So, we can formulate the equation:
1/4 + 1/6 + 1/5 + X = 1
applying LCM, we have:
(15 + 10 + 12 + 60X) = 60
60X = 23
X = 23/60
