Alicia read $\frac{1}{4}$ of a book on Saturday and $\frac{2}{5}$ of it on Sunday. If she read 115 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 130 pages on Saturday, how many pages were left unread
Answer: 182

SOLUTION 1 :

$130

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 = 130

1 unit = 130 ÷ 5
= 26

Step 4 : 7 units = 7 x 26

= 182

182 pages were left unread.

Tamilselvi read $\frac{2}{3}$ of a book on Saturday and $\frac{1}{5}$ of it on Sunday. If she read 320 pages on Saturday, how many pages were left unread
Answer: 64

SOLUTION 1 :

$320

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 = 320

1 unit = 320 ÷ 10

= 32

Step 4 : 2 units = 2 x 32

= 64

64 pages were left unread.

Mithra read $\frac{2}{5}$ of a book on Saturday and $\frac{1}{4}$ of it on Sunday. If she read 344 pages on Saturday, how many pages were left unread

Answer: 301

SOLUTION 1 :

$344

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 = 344

1 unit = 344 ÷ 8

= 43

Step 4 : 7 units = 7 x 43

= 301

301 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 220 pages on Saturday, how many pages were left unread
Answer: 308

SOLUTION 1 :

$220

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 = 220

1 unit = 220 ÷ 5
= 44

Step 4 : 7 units = 7 x 44

= 308

308 pages were left unread.

Haritha read $\frac{2}{3}$ of a book on Saturday and $\frac{1}{5}$ of it on Sunday. If she read 980 pages on Saturday, how many pages were left unread
Answer: 196

$980

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 = 980

1 unit = 980 ÷ 10

= 98

Step 4 : 2 units = 2 x 98

= 196

196 pages were left unread.
