$1200+ $1400 = 2600
Answer:
1200 : 1400 = 6 : 7
The ratio is not in lowest terms so we found an equivalent ratio by simplifying.
Solution:
We can simplify the ratio 1200 : 1400 by dividing both terms by the greatest common factor (GCF).
The GCF of 1200 and 1400 is 200.
Divide both terms by 200.
1200 ÷ 200 = 6
1400 ÷ 200 = 7
Therefore:
1200 : 1400 = 6 : 7
Answer:
The unknown number is -3
Step-by-step explanation:
Represent unknown as x
Write as an equation
12 + (x * 5) = -3
Multiply
12 + 5x = -3
Subtract -5x from both sides of the equation
12 = -3 - 5x
Add 3 to both sides of the equation
15 = -5x
Divide both sides by -5
x = -3
The unknown number is -3
Hope this helps :)
