Which fraction is easier to convert into a decimal?

11/18 or 43/50, explain

Answers

43/50 is easier because 50 is half of 100

Watch this

43/50. Since 50 is HALF of 100 so we multiply 2 by 50 which is 100. But since we multiplied by 2 for the denominator we have to do the same for the numerator so 43 x 2 is equal to 86.

So we get 86/100 which is 0.86

43/50 decimal 0.87

It's easier to turn into a decimal because both are bigger numbers and and closer to each other so it would be easier to divide

Answers

it should be 135





hope this helps

The constant of proportionality is 225.

Given that,

The number of calories burned by a 90-pound cyclist is proportional to the number of hours the cyclist rides. The equation to represent this relationship is y = 225x

Based on the above information, the calculation is as follows:

y = kx

So here the constant should be 225.

Answers

Answer:

It is 150 percent

Step-by-step explanation:

You can find this value by dividing the numerator by the denominator, summing this value to the integer part and multiplying the result by 100%, so:

1 1/2 in percent = (1 + 1/2) × 100% =

(1 + 0.5) × 100% = 1.5 × 100% = 150%

Hope this helps! Sorry if I'm wrong.

Answer:

150%

Step-by-step explanation:

112=1+12

i know that

12

is the same as

1÷2

Therefore:

112=1+(1÷2)

Then using

Long Division for 1 divided by 2

we have

=1+0.5=1.5

Converting our number to a percentage:

1.5×100

=150%
