Zama had 140 packet of chips and each packet hada mass of 50g what is the mass of all packet of chips together ? Write your answer in kg.find the answer using cross multiply
7kg
(140 * 50)/1000 =
To find the mass of all the packets of chips together, we can multiply the number of packets by the mass of each packet.
Given that Zama had 140 packets of chips, and each packet had a mass of 50g, we can set up the equation:
140 packets × 50g = mass of all packets
Now, let's solve this equation using cross multiplication.
First, convert the mass of the packets to kg by dividing by 1000 (since there are 1000g in 1kg):
140 packets × (50g ÷ 1000) = mass of all packets
Now, let's simplify and solve:
140 × 0.05 kg = mass of all packets
7 kg = mass of all packets
Therefore, the mass of all the packets of chips together is 7 kg.
To find the mass of all the packets of chips together, we can multiply the number of packets by the mass of each packet.
Zama had 140 packets of chips, and each packet had a mass of 50g.
Mass of all packets = Number of packets × Mass of each packet
Mass of all packets = 140 × 50g
To convert grams to kilograms, we can divide the mass by 1000, as there are 1000 grams in a kilogram.
Mass of all packets = (140 × 50g) / 1000
Now, let's use cross multiplication to simplify the calculation:
Mass of all packets = (140 × 50) / 1000 kg
Cross multiplying, we have:
Mass of all packets = (140 × 50) ÷ 1000 kg
Mass of all packets = 7000 ÷ 1000 kg
Mass of all packets = 7 kg
Therefore, the mass of all the packets of chips together is 7 kilograms.
