Ответ:
1/2x
Step-by-step explanation:
Dennis read 30% of his book on Tuesday and 1/5 of his book on Wednesday. If he started the book on Tuesday, what fractional part of the book did he have left to read after Wednesday?
Total pages of the book = x
Tuesday = 30%
= (30/100)x
= 3/10x
Wednesday = 1/5x
3/10x + 1/5x
= 3x+2x/10
= 5/10x
= 1/2x
what fractional part of the book did he have left to read after Wednesday
= x - 1/2x
= 2x-x/2
= x/2
= 1/2x
