Answer 1

3 1/3 ÷ 5/3 - 1/10 of 2 ½ + 7/4

= (3 × 3 + 1)/3 ÷ 5/3 – 1/10 of (2 × 2 + 1)/2 + 7/4

= 10/3 ÷ 5/3 - 1/10 of 5/2 + 7/4

[‘of’ simplified]

= 10/3 × 3/5 – ½ × ½ + 7/4 [‘÷’ simplified]

= 2/1 - ¼ + 7/4 [‘×’ simplified]

= (2 × 4)/1 × 4) - (1 × 1)/4 × 1) + (7 × 1)/4 × 1)

= 8/4 - ¼ + 7/4

[Now the denominators are same of all the fractions]

= (8 – 1 + 7)/4 [‘+’ and ‘-‘ simplified]

= 14/4

= 7/2

Answer 2

Solution:-

=> ( 6/7 * 2/3 ) + ( 9/11 + 2/3 )

+ ( 2/3 * 4/9 )

= (12/21) + ( ( 9*3 + 2*11) / (11*3 ) )

+ ( 8/27 )

= 4/7 + ( (27 + 22)/(33) ) + 8/27

= 4/7 + 49/33 + 8/27

= ( (4*33 + 49*7) / (7*33) ) + 8/27

= ( (132 + 343) / ( 231 ) ) + 8/27

= 475/231 + 8/27

= ( 475*27 + 5*231 ) / (231*27)

= ( 12825 + 1155 ) / 6237

= 13980/6237

= 2.241462241

i hope it helps you.
