Question

who will give my answer I will mark as a brainlist and follow him or her after given the answer clearly full question answer ok if someone will write faltu things on it I will not do anything ​

Answer 1

→given ,car covers 7.8 km in 1.4 hours

then ,

             1 hour =x

        1.4 hours =7.8   (cross multiplication)

1.4x=7.8

x=7.8/1.4

x=78/14

x=5.5km

→given, side of square=11.11m

w.k.t. Area of square= s²

         Area of square=11.11²

                                  =123.4321

→1 metre=100cm

1 cm= 1/100 m

10 cm= 1/10 metres or 0.1 metre

1 km= 100000cm or 10 power 6

1 cm= 1/100000km

10 cm= 1/10000 km or 10 power -5

→17 1/2 ÷5/7

=34+1/2 ÷ 5/7

=35/2÷ 5/7

=35/2×7/5

=7×7/2

=49/2 or 24.5 or 24 1/2

→17/15 × x = 85/75

transpose 17/15 to right side then it will be division

x = 85/75 ÷17/15

x = 85/75 × 15/17

x = 1275/1275

x = 1
