Alicia read $\frac{1}{4}$ of a book on Saturday and $\frac{2}{5}$ of it on Sunday. If she read 305 pages on Saturday, how many pages were left unread

Answer:_______________

Alicia read $\frac{1}{4}$ of a book on Saturday and $\frac{2}{5}$ of it on Sunday. If she read 295 pages on Saturday, how many pages were left unread
Answer: 413

SOLUTION 1 :

$295

Sunday

Left

Step 1: $\frac{1}{4}$ + $\frac{2}{5}$ = $\frac{5}{20}$ + $\frac{8}{20}$ = $\frac{13}{20}$

Step 2: $\frac{20}{20}$ - $\frac{13}{20}$ = $\frac{7}{20}$

Step 3 : 5 units = 295

1 unit = 295 ÷ 5
= 59

Step 4 : 7 units = 7 x 59

= 413

413 pages were left unread.

Swathi read $\frac{2}{3}$ of a book on Saturday and $\frac{1}{5}$ of it on Sunday. If she read 560 pages on Saturday, how many pages were left unread
Answer: 112

SOLUTION 1 :

$560

Sunday

Left

Step 1 : $\frac{2}{3}$ + $\frac{1}{5}$ = $\frac{10}{15}$ + $\frac{3}{15}$

= $\frac{13}{15}$

Step 2 : $\frac{15}{15}$ - $\frac{13}{15}$ = $\frac{2}{15}$ (left)

Step 3 : 10 units = 560

1 unit = 560 ÷ 10

= 56

Step 4 : 2 units = 2 x 56

= 112

112 pages were left unread.

Kumutha read $\frac{2}{5}$ of a book on Saturday and $\frac{1}{4}$ of it on Sunday. If she read 456 pages on Saturday, how many pages were left unread

Answer: 399

SOLUTION 1 :

$456

Sunday

Left

Step 1 : $\frac{2}{5}$ + $\frac{1}{4}$ = $\frac{8}{20}$ + $\frac{5}{20}$

= $\frac{13}{20}$

Step 2 : $\frac{20}{20}$ - $\frac{13}{20}$ = $\frac{7}{20}$

Step 3 : 8 units = 456

1 unit = 456 ÷ 8

= 57

Step 4 : 7 units = 7 x 57

= 399

399 pages were left unread.

Alicia read $\frac{1}{4}$ of a book on Saturday and $\frac{2}{5}$ of it on Sunday. If she read 330 pages on Saturday, how many pages were left unread

Step 3 : 5 units = 330

1 unit = 330 ÷ 5
= 66

Step 4 : 7 units = 7 x 66

= 462

462 pages were left unread.

= $\frac{13}{15}$

Step 2 : $\frac{15}{15}$ - $\frac{13}{15}$ = $\frac{2}{15}$ (left)

Step 3 : 10 units = 530

1 unit = 530 ÷ 10

= 53

Step 4 : 2 units = 2 x 53
