Answer:_______________

Thamarai read $\frac{2}{5}$ of a book on Saturday and $\frac{1}{4}$ of it on Sunday. If she read 224 pages on Saturday, how many pages were left unread

Answer: 196

SOLUTION 1 :

$224

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 = 224

1 unit = 224 ÷ 8

= 28

Step 4 : 7 units = 7 x 28

= 196

196 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 730 pages on Saturday, how many pages were left unread
Answer: 1022

SOLUTION 1 :

$730

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 = 730

1 unit = 730 ÷ 5
= 146

Step 4 : 7 units = 7 x 146

= 1022

1022 pages were left unread.

Tulasi read $\frac{2}{3}$ of a book on Saturday and $\frac{1}{5}$ of it on Sunday. If she read 430 pages on Saturday, how many pages were left unread
Answer: 86

SOLUTION 1 :

$430

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 = 430

1 unit = 430 ÷ 10

= 43

Step 4 : 2 units = 2 x 43

= 86

86 pages were left unread.

Savithri read $\frac{2}{5}$ of a book on Saturday and $\frac{1}{4}$ of it on Sunday. If she read 392 pages on Saturday, how many pages were left unread

Answer: 343

SOLUTION 1 :

$392

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 = 392

1 unit = 392 ÷ 8

= 49

Step 4 : 7 units = 7 x 49

= 343

343 pages were left unread.
