Question

tina types 30 words per minute and james types 65 words per minute. what is the ratio of words per minute that tina types to the words per minute that james types?
a. 5:1
b. 6:1
c. 6:5
d. 6:13

Explanation:

Step1: Identify the values

Tina's typing speed: 30 words per minute. James's typing speed: 65 words per minute.

Step2: Form the ratio

Ratio of Tina's speed to James's speed: $\frac{30}{65}$

Step3: Simplify the ratio

Divide numerator and denominator by their greatest common divisor, which is 5. $\frac{30\div5}{65\div5} = \frac{6}{13}$? Wait, no, wait. Wait, 30 and 65. Wait, 30 divided by 5 is 6, 65 divided by 5 is 13? Wait, no, the question is Tina to James. Wait, 30:65. Simplify by dividing both by 5: 6:13? Wait, no, the options are A.5:1, B.6:1, C.6:5, D.6:13. Wait, wait, maybe I made a mistake. Wait, Tina types 30, James types 65. So 30:65. Let's divide numerator and denominator by 5: 6:13. So the ratio is 6:13, which is option D. Wait, but let me check again. 30 and 65. GCD of 30 and 65 is 5. 30 ÷5=6, 65 ÷5=13. So 6:13. So the answer is D.

Answer:

D. 6:13
