Representing 3 and one tenth as decimal by 3.1
<u>Step-by-step explanation:</u>
Here 3 is the whole number.
1 tenth is nothing but 
.
= 0.1
When we write numerals with tenths using the decimals we can use a decimal point also the tenths positioned to the right of the decimal point. The tenth place is denoted as immediately right to the decimal point.
So it is represented as 3.1.
Answer:
3 Pounds for 15.10
Step-by-step explanation:
find a common multiplier (12)
4 pounds ($21.50) [×3] 12 pounds ($64.50)
3 pounds ($15.50) [×4] 12 pounds ($ 62)
you save $2.50
Answer:
1,000
Step-by-step explanation:
60% of 1,000 is equal to 600
The first way is to cross multiply
4/5 = 28/x
4x = 5*28
4x = 140
4x/4 = 140/4
x = 35 which is the answer
=============================================
The second method is to note the denominators 4 and 28, and to ask yourself "what times 4 gets me 28?". The answer being 7, so 7*4 = 28. If you multiply top and bottom of the fraction 4/5 by 7, then you end up with 7*4 = 28 up top and 7*5 = 35 down below. This is another way of seeing how 4/5 = 28/35
Either way, the answer is x = 35
Answer:
z=4
Step-by-step explanation:
If z=x/y and x=10 and y=2.5 then,
z=10/2.5
10/2.5=4
