In meter, centimeter and millimeter largest unit is meter, then centimeter and then milimeter. For conversion 1 m=100 cm, 1 m=1000 cm.

Convert all the number to same unit for compare with each other.

First option is 7560 m.

Second option is,


7.56*10\text{ cm}*\frac{1\text{ m}}{100\text{ cm}}=0.756\text{ m}

Third option 7.56 m is already in meter.

Consider the fourth option,


7.56*10^4\text{ m=75600 m}

Consider option fifth,


7.56*10^4\text{ cm}*\frac{1\text{ m}}{100\text{ cm}}=756\text{ m}

Now check which digit is largest.

Largest is 75600 so first blank digit is ,


7.56*10^4\text{ m}

Second larget is 7560. So second blank digit is 7560 m.

Third largest is 756 m, So third blank digit is,


7.56*10^4\text{ cm}

Fourth largest is 7.56 m so in fourth blank digit is,

7.56 m

Fifth largest or smallest digit is 0.756 m. So in last blank digit is,


7.56*10\text{ cm}
