Answer:
3.7
Step-by-step explanation:
To change a fraction to a decimal, just divide the numerator with the denominator. Instead of placing the remainder over the divisor, continue to solve until it is answered (unless it's a repeating decimal.)
Divide 7 with 10:
7/10 = 0.7
Remember that there is a whole number, 3. Add that to the decimal you have gotten:
3 + 0.7 = 3.7
3.7 is your answer.

Answer:
2.25 km to go
Step-by-step explanation:
In order to get this answer, you have to figure out how many km 10% is, 0.1125. Then multiply that by the remaining 20% because he already finished 80% of the trail. So, 0.1125 x 20 = 2.25.
Hope this helps! :)

First you -4 from x so you have to do the opposite which is to add 4
Answer:
Step-by-step explanation:
22 liters of petrol to travel 259.6 km
1litres will travel 259.6/22 km
1litres will travel 11.8km
:2013.2km needs 2013.2/11.8litre
:2013.2km needs 170.61litres
And 1 liter of petrol costs $ 1.99
So 742.88 litres will cost $1.99×170.61
= $339.51
⓵ Write down your complete equation:
x + ¾ = 9/8
⓶ Solve the equation in order to find the value of “x”:
x + ¾ = 9/8
- ¾ - ¾
x = 9/8 - ¾
There a 3 simple steps to subtract fractions:
⒈ Make sure the bottom numbers (the denominators) are the same.
9/8 - ¾ → They don’t have the same denominator.
You need to multiply the top number and the bottom number of ¾ by 2 :
3 (x2) 6
—- = ——
4 (x2) 8
So now you are left with : 9/8 - 6/8
⒉ Subtract the top numbers (the numerators). Put the answer over the same denominator :
9 - 6 = 3 → ⅜
⒊ Simplify the fraction (if needed) :
⅜ → The fraction is already simplified.
⇨ Your answer is: x = ⅜
There you go! I really hope this helped, if there’s anything just let me know! ☻
