sorry it took me a while to get to it.
What about 15
Its okay thanks
WHAT THE HECK IS THIS
Where are the answers
Ok I’m in conexxus can someone post the answers that have conexxus?
To write a ratio in simplest form, you need to find the greatest common divisor (GCD) of the two numbers and divide both numbers by it.
1. For the ratio 45:15, the GCD of 45 and 15 is 15. Dividing both numbers by 15, we get the simplified ratio of 3:1. Therefore, the answer is b) 3:1.
4. The ratio of the number of tickets Jeanne sold to the number of tickets Jake sold is 12:39. The GCD of 12 and 39 is 3. Dividing both numbers by 3, we get the simplified ratio of 4:13.
5. To find the unit rate, you divide the total amount used (62.6 gallons) by the number of months (10 months). Therefore, the unit rate is 62.6 gallons / 10 months = 6.26 gallons/month. Rounding to the nearest tenth, the answer is c) 6.3 gallons/month.
6. To find the unit price, you divide the total cost ($1.75) by the number of bagels (5 bagels). Therefore, the unit price is $1.75 / 5 bagels = $0.35 per bagel. The answer is c) $0.35 per bagel.
9. If the scale factor is 4, then the larger rectangle is four times the size of the smaller rectangle. If the perimeter of the smaller rectangle is 20 cm, then the perimeter of the larger rectangle is 4 * 20 cm = 80 cm. The answer is b) 80 cm.
10. If 1 cm on the map represents 30 miles in reality, then 3.7 cm on the map represents 3.7 * 30 miles = 111 miles. Rounding to the nearest 10 miles, the answer is d) 110 miles.
13. To write the ratio 30:48 as a fraction in simplest form, divide both numbers by their GCD, which is 6. The simplified fraction is 5/8.
14. The ratio 24 to 20 can be written as the fraction 24/20. Since both numbers are divisible by 4, divide both by 4. The simplified fraction is 6/5.
15. To write 6 out of 9 as a ratio fraction, simply write it as 6/9. However, you can simplify this fraction by dividing both numbers by their GCD, which is 3. The simplified fraction is 2/3.
16. The male-to-female ratio of 46 to 54 can be written as the fraction 46/54. Since both numbers are divisible by 2, divide both by 2. The simplified fraction is 23/27.
