Respuesta :
A common denominator of 6 and 4 is 12. That is the Least Common Denominator, the LCD. In 12 days it would be the 27th of February. There you go.
Answer:
27th February is answer .
Step-by-step explanation:
Brain has math test = after every six days
His Science test = after every four days
Next common multiplier will be chosen by taking their Least common multiplier is
6 = 2x3
4 = 2x2
LCM = 2 x 2 x 3 = 12
After every 12 days Brain will have both test of Math and Science
If first test was on 15th Feb then next both test will be
15th + 12th = 27th February
Next date for both test will be 27th February.
