Answer:
x=21/40
Step-by-step explanation:
First get common denominators
3/8 *5 to top and bottom is now 15/40
3/20 *2 to top and bottom is now 6/40
isolate the X
x-15/40=6/40
+15/40 +15/40
x=21/40
Answer:
x = [tex]\frac{21}{40}[/tex]
Step-by-step explanation:
Given
x - [tex]\frac{3}{8}[/tex] = [tex]\frac{3}{20}[/tex]
Multiply through by 40 ( the LCM of 8 and 20 ) to clear the fractions
40x - 15 = 6 ( add 15 to both sides )
40x = 21 ( divide both sides by 40 )
x = [tex]\frac{21}{40}[/tex]
