The total cherries have bought by Tiffany and Linda was [tex]\frac{7}{10}[/tex] kg.
Further Explanation
Let's say that:
Tiffany = x
Linda = y
From the problem given, we have got these two equations:
[tex]x=\frac{2}{5}[/tex] .......... (1)
[tex]y = x -\frac{1}{10}[/tex] ......... (2)
First step, we are going to find the y variable:
[tex]\boxed {y= x-\frac{1}{10} }\\ \boxed {y = \frac{2}{5} - \frac{1}{10} }\\\boxed {y = \frac{4-1}{10} = \frac{3}{10} }[/tex]
In fraction additional, when the denominators are different we need to find a common denominator, for the above equation is 10. Multiply each numerator with the same number as the denominator multiply with to get the common denominator.
then we are going to calculate the total cherries which is:
[tex]\boxed {x+y = \frac{2}{5} + \frac{3}{10} }\\\boxed {= \frac{4+3}{10} = \frac{7}{10} }[/tex]
So the total cherries they bought altogether was [tex]\frac{7}{10}[/tex] kg.
