Step-by-step explanation: In mathematics, solving word problem required knowledge and skills in basic mathematics that will improve your analytical and critical thinking skills.
In the given problem, you need to apply your knowledge and skills in alegbra and basic math especially in fraction.
Problem
6 4/5 decreased by 2 2/3
Key points
decreased means addition
Solution
Create mathematical equation first, according to the statement given.
6 4/5 - 2 2/3
In adding and subtracting dissimilar fraction, it requires LCD/LCM to convert into similar fraction.
The LCD of 5 and 3 is 15.
4/5 = 12/15
2/3 = 10/15
= 6 12/15 - 2 10/15
Subtract the fraction first and next the whole number.
12/15 - 10/15 = 2/15 6 - 2 = 4 Therefore, the answer is 4 2/15 , I hope it helps.
Answers & Comments
Answer:
4. 4 2/15
5. 7 5/6
Step-by-step explanation:
4.
n = 6 4/5 - 2 2/3
n = 6 12/15 - 2 10/15
n = 4 2/15
5.
n = 2 1/3 + 5 1/2
n = 2 2/6 + 5 3/6
n = 7 5/6
