Is 1.625 greater than, less than, or equal to 1.7
Answers
If the 5 were to round the 2 it would be 1.63 and the 3 cannot be rounded up so if we looked at this this way: 1.6 and 1.7 we know that 1.7 would be greater.

The bakery can make 420 bagels in 20 hours that the rate per hour would be 21.
What is Ratio?
A ratio is defined as a relationship between two quantities, it is expressed as one divided by the other
What are Arithmetic operations?
Arithmetic operations can also be specified by adding, subtracting, dividing, and multiplying built-in functions.
/ Division operation: Divides left-hand operand by right-hand operand
For example 4/2 = 2
We have been given that the bakery can make 210 bagels in 10 hours.
We have to determine the number of bagels can they bake in 20 hours.
Let x bagel would be they bake in 20 hours
We can write this as a ratio as
210 bagel : 10 hours = x bagel : 20 hours
⇒ 210/10 = x/20
⇒ 21 = x/20
⇒ x = 21×20
⇒ x = 420
And rate per hour would be 420/20 = 21
Therefore, they can bake 420 bagels in 20 hours.

10 hrs x2 = 20 hrs
210 bagels x2 = 420 bagels
All you had to do was multiply the original number by 2 since you had to find the number in 20 hours and you already had the number for 10. What you do to the top of the fraction, you must do to the top. So, there are 420 bagels in 20 hours.
Next, you must find the unit rate. To do this, you have to divide the top and bottom of the fraction by the greatest common factor. The top of the fraction is 10, and 10 can go into 210, so that must be our GCF (greatest common factor). 210 divided by 10 is 21 (just take the 0 off the end!) Then, 10 divided by 10 is 1. So, your unit rate is 21 bagels per hour.

Dividing the weight of the radioactive isotope from 4 halves that is 16, the left weight of the radioactive isotope after 4 half-lives is
⇒ 10.3 grams
Given that,
The half-life of a radioactive isotope is the time it takes for a quantity of the isotope to be reduced to half its initial mass.
Here, Starting weight of the radioactive isotope is, 165 grams
Hence, the left weight of the radioactive isotope after 4 half-lives is,
⇒
