4.2 the 2 is in the tenths place so you round it using the 3 because it is the first one behind it and 3 is less than 5 so it just stays at 2 so your answer is 4.2

]4.23 rounded to the nearest tenth im not going to tell you but if its 5 and higher you round up to the nearest tenth and if its below five you round down to the nearest ten or you can google it but first ask permission hope that help and remember a decimal only holds a place hope I helped!!!!
