[tex] \text{Step \: 1 : }[/tex] Convert the mixed number into an improper fraction.
[tex] \tt➵ \: \frac{4 \times 3 + 2}{3} \: \div \: \frac{2 \times 3 + 1}{3} [/tex]

[tex] \text{Step \: 2} : [/tex] If any number or fraction is divided by a fraction,we multiply the dividend by the reciprocal of the divisor. Reciprocal of any number or any fraction can be obtained by interchanging the position of numerator and denominator.
[tex] \tt{ \: ➵ \: \frac{14}{3} \: \times \: \frac{3}{7} }[/tex]
[tex] \text{Step \: 3} : [/tex] To multiply one fraction by another , multiply the numerators for the numerator and multiply the denominators for its denominator and reduce the fraction obtained after multiplication into lowest term.

To find the quotient Three-fourths divided by one-eighth,
What do I need to multiply to get my quotation
Answer:
6
Step-by-step explanation:
I believe this answer is 6 because you need to get common denominators first. So the fractions would be 6/8 and 1/8. Then you do the reciprocal which is 6/8 times 8/1. Then you multiply the numerators 6 and 8. Then the denominators 8 and 1. Then you do 48 divided by 8 (48/8) which is 6. You got this! :)

An average fly has a mass of 0.048 grams. An average ant has a mass of 3.12 x 10^-3grams
Would 3.99 million flies or 47,000.000 ants have a greater mass?
Approxmately how much greater, in grams, would the greater mass be? Justity your answers Respond in the space provided
Answer:
the flies have a greater mass
Step-by-step explanation:
First, we should solve 10^-3 = 0.001 "for the ants" it is NOT negative now 0.001 times 3.12=0.00312 to find the total fly mass we should just multiply 0.048 times 3990000=191520 and for the ants 0.00312 times 47million=146640 so now the answer would be that the flies has a greater mass
Answer:
the flight have greater mass

plz heeeeeelp asap
Answer:
1.83 square feet
Step-by-step explanation:
42/23=1.83
She paints her bedroom at the rate of 1.83 square feet per hour.
Given that,
Caitlin is painting her bedroom. She paints 42 square feet in 23 hours. At this rate, how many square feet can she paint in one hour is to be determined.
The rate of change is defined as the change in value with the rest of the time is called the rate of change.
What is the Ratio?The ratio can be defined as the proportion of the fraction of one quantity towards others. e.g.- water in milk.
Here,
She paints 42 square feet in 23 hours.
Area painted = 42 square feet
time = 23 hours
Rate = area painted / time
= 42 / 23
= 1.83
Thus, she paints her bedroom at the rate of 1.83 square feet per hour.

Hey! Elizabeth here! I would say the answer to your current question is Planet A. or C. The Planet A. has all of the Earth Requirement(at least I thinks..), same with Planet C!
