Answer:
2.25 divided by 0.6 : Yes and 5.2 divided by 8, 3.63 divided by 3, 71.1 divided by 9 : No
Step-by-step explanation:
We have that when two numbers are divided, they can be written in the form , where p is the dividend and q is the divisor.
Now, when we divide 5.2 by 8, we can write
Also, the division 3.63 by 3, can be written as = 1.21
Further, when we divide 71.1 by 3, we can write = 23.7
We can see that above divisions are easy divisions and do not require to write any type of 0 in the numerator.
Moreover, when we divide 2.25 by 0.6, we can write =
.
So, we get that in the last division, we need to write a zero in order to multiply the numerator with 10 for easy division.
Hence, 2.25 divided by 0.6 : Yes and 5.2 divided by 8, 3.63 divided by 3, 71.1 divided by 9 : No
Answer: The cost of one sandwich is $4.25 and the cost of one cup of coffee is $2.25.
Step-by-step explanation:
Let x be the cost of one sandwich and y be the cost of one cup of coffee.
By considering the given situation, we have the following equations :-
Multiply 2 on both sides of equation (2) , we get
Subtract equation (1) from equation (3), we get
Put value of y in (1), we get
Hence, the cost of one sandwich is $4.25 and the cost of one cup of coffee is $2.25.
